Academic libraries moving on up the creative industries track

Sant-Geronikolou, S., Martizan-Avila, D., & Koulouris, A. (2018)
Conference Paper 10th International Meeting on Information Knowledge and Action,Sao Paolo, Basil, June 18-22, 2018

Abstract

As governments around the world are beginning to recognize the role of creativity in the promotion of innovation and competitive advantage in a Global Knowledge Economy (GKE), Creative Knowledge-based Industries are becoming the focus of attention. Nevertheless, and in spite of the rise of Big Data, the prevailing absence of systematic library collection of activity data perpetuates the persistence of traditionalist and myopic approaches that tend to overlook the nexus between libraries and creativity while perceiving libraries as exclusively or basically collection gatekeepers, information brokers, and content providers. Given the universally acknowledged fact that the central value of the library is clearly creative, we embarked on the exploration of the academic library position within the Creative Industries system, as seen through the Ibero-American library community lens. In this vein, and following a literature review that focused on the interpretation of the intensity of creative in libraries, value, and content across different Creative Industries classification models, our survey within the library expert community attempts to investigate the relationship between academic libraries and the creative industries (CI) realm. Our overarching goal is to facilitate the articulation of targeted recommendations and to contribute to the conceptual foundations guiding the formation of a special interest group that will streamline the academic librarianship community response to this challenging area.

Journal Paper Journal of Integrated Information & Management, 3(1), 7-13.

Abstract

Purpose - This paper seeks to encourage reflections on the extent to which a one-shot workshop can help about-to-be information Professionals understand and appreciate the gamut of complexities and challenges associated with library position in the emerging Learning Analytics (LA) ecosystem. Design/methodology/approach – It focuses on the description of the experience in organizing a workshop at the Department of Archival, Library & Information Studies (ALIS) of the University of West Attica. Building upon desk and primary research findings, organizers envisioned providing a valuable opportunity for senior students to collaboratively help identify the hidden value of student generated data for the support of their success and retention. Analyses of lessons learned, student viewpoints and recommendations for the future, all aim to contribute knowledge to the meta-community of Higher Education library professionals that are exploring ways to streamline their smooth integration into the educational process taking full advantage of new ICT capabilities. Findings- Students seemed to have quickly developed a substantial understanding of the risks and opportunities involved in this type of innovation as reflected on detected differences between a set of pre and post-workshop survey indicators. Furthermore, student evaluations on workshop design, delivery and content quality have provided valuable input on its usefulness and a set of recommendations for change. Originality/value - It presents and analyses observations of the first Greek LIS community initiation experience to current Learning Analytics landscape, a topic germane to university libraries that could eventually influence New Information Professionals’ mindset and aspirations.

Conference Paper In A. Kavoura, D. Sakas, & P. Tomaras (Eds.) Strategic Innovative Marketing. Springer Proceedings in Business and Economics, pp. 727–733. Springer International Publishing.

Abstract

The purpose of this paper is to investigate the application of text classification in Hypatia, the digital library of Technological Educational Institute of Athens, in order to provide an automated classification tool as an alternative to manual assignments. The cru-cial point in text classification is the selection of the most important term-words for docu-ment representation. Classic weighting method TF.IDF was investigated. Our document collection consists of 718 abstracts in Medicine, Tourism and Food Technology. Classifica-tion was conducted utilizing 14 classifiers available on WEKA. Classification process yielded an excellent ~97% precision score.

Abstract

Applications of clustering and classification techniques can be proved very significant in both digital and physical (paper-based) libraries. The most essential application, document classification and clustering, is crucial for the content that is produced and maintained in digital libraries, repositories, databases, social media, blogs etc., based on various tags and ontology elements, transcending the traditional library-oriented classification schemes. Other applications with very useful and beneficial role in the new digital library environment involve document routing, summarization and query expansion. Paper-based libraries can benefit as well since classification combined with advanced material characterization techniques such as FTIR (Fourier Transform InfraRed spectroscopy) can be vital for the study and prevention of material deterioration. An improved two-level self-organizing clustering architecture is proposed in order to enhance the discrimination capacity of the learning space, prior to classification, yielding promising results when applied to the above mentioned library tasks.

NLP as a Communication Strategy Tool in Libraries

Koulouris, A., Sakas, D., & Giannakopoulos, G. (2015)
Conference Paper In G. Giannakopoulos, D. Sakas, & D. Kyriaki-Manessi (Eds.) AIP Conference Proceedings, Proceedings of the 4th International Conference on Integrated Information (IC-ININFO 2014),Madrid, Spain, September 5-8, 2014, vol. 1644, pp. 83-90.

Abstract

The role of communication is a catalyst for the proper function of an organization. This paper focuses on libraries, where the communication is crucial for their success. In our opinion, libraries in Greece are suffering from the lack of communication and marketing strategy. Communication has many forms and manifestations. A key aspect of communication is body language, which has a dominant communication tool the neuro-linguistic programming (NLP). The body language is a system that expresses and transfers messages, thoughts and emotions. More and more organizations in the public sector and companies in the private sector base their success on the communication skills of their personnel. The NLP suggests several methods to obtain excellent relations in the workplace and to develop ideal communication. The NLP theory is mainly based on the development of standards (communication model) that guarantees the expected results. This research was conducted and analyzed in two parts, the qualitative and the quantitative. The findings mainly confirm the need for proper communication within libraries. In the qualitative research, the interviewees were aware of communication issues, although some gaps in that knowledge were observed. Even this slightly lack of knowledge, highlights the need for constant information through educational programs. This is particularly necessary for senior executives of libraries, who should attend relevant seminars and refresh their knowledge on communication related issues.

Enhanced OAI-PMH services for metadata sharing in heterogeneous environments

Houssos, N., Stamatis, K., Koutsourakis, P., Kapidakis, S., Garoufallou, E., & Koulouris, A. (2014)
Journal Paper Library Review, 63(6/7), 465–489

Abstract

Purpose – This paper aims to propose a toolset that enables individual digital collections owners to satisfy the requirements of aggregators even in cases where their IT and software infrastructure is limited and does not support them inherently. Managers of repositories/digital collections face the challenge of exposing their data via Open Archives Initiative – Protocol for Metadata Harvesting (OAI-PMH) to multiple aggregators and conforming to their possibly differing requirements, for example on output metadata schemas and selective harvesting. Design/methodology/approach – The authors developed a software server that is able to wrap existing systems or even metadata records in plain files as OAI-PMH sources. They analysed the functionality of OAI-PMH data providers in a flow of discrete steps and used a software library to modularise the software for these steps so that the whole process can be easily customised to the needs of each pair of OAI-PMH data provider and service provider. The developed server includes a mechanism for the implementation of schema mappings using an XML specification that can be defined by non-IT personnel, for example metadata experts. The server has been applied in various real-life use cases, in particular for providing content to Europeana.Findings – It has been concluded through real-life use cases that it is indeed possible and feasible in practice to expose metadata records of digital collections via OAI-PMH even when the data sources do not support the required protocols and standards. Even advanced OAI-PMH features like selective harvesting can be supported. Mappings between input and output schemas in many practical cases can be implemented entirely or to a large extent as XML specifications by metadata experts instead of software developers. Practical implications – Exposing data via OAI-PMH to aggregators like Europeana is made feasible/easier for digital collections owners, even when their software infrastructure does not inherently support the required protocols and standards. Originality/value – The approach is original and applicable in practice to diverse technology environments, effectively addressing the indisputable fact of the heterogeneity of software and systems used to implement digital repositories and collections worldwide.

Austerity measures in Greece and their impact on higher education

Koulouris, A., Moniarou-Papaconstantinou, V., & Kyriaki-Manessi, D. (2014)
Journal Paper Procedia - Social and Behavioral Sciences 147, 518–526

The present study examines the impact of austerity measures on the academic community. The Technological Educational Institute of Athens served as our case study. It was selected because it is the second largest higher education institution in Greece, and has students of a diverse socio- economic background. Data were obtained through an analysis of institution financial statements and other documents depicting budgets, human resources, infrastructure, in an attempt to study their impact on the resulting quality of education. In addition, through the use of questionnaires we evaluated the impact of austerity measures and the economic crisis on both academic staff and students in relation to their performance, the quality of education, and their plans for educational and professional trajectories. Finally, and given the pending merging or even closure of some departments, faculties and/or institutions throughout the country, we examined the effects on people's attitudes towards educational and research activities.

Solving aggregation problems of Greek cultural and educational repositories in the framework of Europeana

Garoufallou, E., Banos, V., & Koulouris, A. (2013)
Journal Paper International Journal of Metadata, Semantics and Ontologies (IJMSO), 8(2), 134–144.

The paper describes a set of software tools and methodologies followed by the Hellenic Aggregator and Greek cultural, educational and scientific institutions in order to contribute their content to Europeana. The software tools are presented and their impact on the publishing, aggregation and dissemination process of Greek content to Europeana is described. The work of the Hellenic Aggregator, the methodologies developed and the new software tools, which were created, improved the publishing process of Greek institutions and promoted their content to Europeana. During this process, difficult technical challenges were overcome and a clear path has been created for Greek content providers who would like to publish their content to Europeana. Without these software and methodologies, harvesting Greek digital content from Europeana would not be possible. The present study outlines also the work on supporting Europeana Semantic Elements (ESE) metadata schema.

Libraries in crisis: a glimpse over Greece and Cyprus

Giannakopoulos, G., Koulouris, A., & Kokkinos, D. (2014)
Journal Paper Procedia - Social and Behavioral Sciences, , 147, 411–417.

The current global financial crisis is the biggest economic upheaval for all libraries around the world and especially for those in Southern Europe. Due to this crisis, Greek and Cypriot libraries face many problems deriving mostly from their state funding and personnel reduction. The paper focuses on the effects on operation and services of Greek and Cypriot libraries, and the impact caused by salary reductions and personnel layoffs on their actual survival. A survey was conducted through an online questionnaire available in Lime Survey to all Greek and Cypriot academic, public and special libraries. Responses were gathered and analysed. In conclusion, the paper proposes some ideas for the development of new services and activities that may help libraries to deal with the effects of financial crisis and help them stay alive and to reactivate their users support.

Evaluation of the e-class platform of the LIS Dept., TEI of Athens

Zervos, S., Kyriaki-Manessi, D., Koulouris, A., Giannakopoulos, G., & Kouis, D. (2013).
Journal Paper Procedia - Social and Behavioral Sciences, 73, 727–735.

The Department of Library Science and Information Systems of the TEI of Athens is using a Moodle installation as its eclass platform for the past four semesters. Moodle is a freely distributed open source software, and has been one of the most popular Course Management Systems. The faculty has invested a significant amount of time and effort and has created 50 online courses, which provide students with all the necessary course material (multiple bibliographies, presentations, e-books and other text and multimedia resources). The online resources also include activity modules, assignments and quizzes that utilize the interactive and collaborative environment of Moodle. This study presents the evaluation of the department’s e-class, which has been based on two online questionnaires, one addressed to the faculty and the other to the students. The questionnaires attempted to collect data concerning the users’ attitudes and profiles (visiting frequency, favorite activities) and their opinions about the functionality and usefulness of the eclass in enhancing the teaching and learning experience. The results fully confirm the faculty’s view that the e-class is an indispensable addition to the departments teaching tools and demonstrate that it is extensively used and highly appreciated by both faculty and students.

Institutional repository policies: best practices for encouraging self-archiving

Koulouris, A., Kyriaki-Manessi, D., Giannakopoulos, G., & Zervos, S. (2013)
Journal Paper Procedia - Social and Behavioral Sciences, 73, 769–776

Over the past year, many Institutional Repositories have been launched by Greek Universities. In this framework, the Library of the Technological Educational Institute of Athens has designed and is launching an Institutional Repository containing Faculty's published and unpublished work, students’ theses and a major “Institutional Archival Collection”. However, the library had a long history of mistrust, mainly deriving from its long periods of understaffing and poor services. Thus, it was evident that the Institute had to rebuild trust and promote the IR. The first step in launching IRs was to set up policies regarding the content, the self-archiving procedure, the use of personalized services for users and the introduction of relevant routines. In the process, it became apparent that the organizational culture had to be redesigned. These lead to the formulation of ‘best practices’ which would secure the effective and widespread use of the repository by all members of the academic community. A bibliographic review was carried out regarding repository policies. In addition, observation techniques were used in assessing the use of the repository. Furthermore, a questionnaire was distributed to users in order to assess the effectiveness, ease of use and level of understanding of the repository's functions.

Policy route map for academic libraries' digital content

Koulouris, A., & Kapidakis, S. (2012)
Journal Paper Journal of Librarianship and Information Science (JOLIS),, 44(3), 163–173.

This paper presents a policy decision tree for digital information management in academic libraries. The decision tree is a policy guide, which offers alternative access and reproduction policy solutions according to the prevailing circumstances (for example acquisition method, copyright ownership). It refers to the digital information life cycle, focusing mostly on its creation (digitized or born-digital), acquisition, copyright and availability. The resulting decision tree is based on a policy model, which was initially divided into two branches – one for digitized and one for born-digital information. The decision tree simplifies and unifies commonly adopted rules which were identified through a questionnaire survey on the access and reproduction policies of 67 digital collections in 34 multidisciplinary libraries (national, academic, public, special, etc.) from 13 countries. The results of the decision tree are used to propose alternative policies.

Exploratory research regarding faculty attitudes towards the institutional repository and self archiving

Kyriaki-Manessi, D., Koulouris, A., Giannakopoulos, G., & Zervos, S. (2013).
Journal Paper Procedia - Social and Behavioral Sciences, , 73, 777–784.

Over the past year the Library of the TEI of Athens has launched an Institutional Repository containing Faculty’s published and unpublished work, students’ theses and a major collection called “Institutional Archives”. The latter was also used as a vehicle for promoting the Repository and had attracted a lot of interest from all faculty members and the Institute’s administration. While in the making, special effort was made to secure faculty’s understanding of the undertaking and faculty’s participation. Information was communicated through e- letters from the Library, the Deans and the Institute’s President as well. A web site was developed and a feedback mechanism was set in place. A system of approaching individually each faculty member and create customized lists of publications to be incorporated in the IR had given surprisingly good results. The assessment of these measures in relation to faculty’s willingness to participate in the IR is examined. Furthermore, faculty’s attitude towards self-archiving is also examined. A bibliographic review was carried out regarding faculty attitudes and factors that shape it. A questionnaire was distributed to all faculty members in order to assess the effectiveness of the communication system and the degree of their willingness to practice self archiving. This explored faculty reactions and determined the effectiveness of the IR. Major findings include the faculty’s positive reception of the IR due to the fact that the information was communicated properly through the aforementioned mechanism and their enthusiasm and overcoming of hesitations after understanding the capabilities of the IR.

Conference Paper In G. Giannakopoulos & D. Sakas (Eds.), Proceedings of the International Conference on Integrated Information (IC-ININFO 2011), Kos Island, Greece, September 29-October 3, 2011, pp. 254–257. Piraeus: IDAS.

The effects of book and paper conservation treatments on the intrinsic data of the artifacts are examined. The tangible data present in an object are grouped in three layers, with the third layer being associated with the object’s material properties. The wealth of information that can be drawn from the data of the third layer and their significance is discussed. The obfuscation of critical data or their complete loss after specific treatments is a possible outcome, and conservators, stakeholders and the public should be aware of what may be lost after a conservation intervention.

Aggregating Metadata for Europeana: The Greek paradigm

Koulouris, A., Banos, V., & Garoufallou, E. (2011)
Conference Paper In G. Giannakopoulos & D. Sakas (Eds.), Proceedings of the International Conference on Integrated Information (IC-ININFO 2011), Kos Island, Greece, September 29-October 3, 2011, pp. 198–201. Piraeus: IDAS.

Europeana is an evolving service that tries to be a single access point for Europe’s cultural heritage. The metadata aggregation for Europeana is a procedure that needs interoperability and software tools for transforming metadata to Europeana Semantic Elements (ESE). This aggregation imposes requirements difficult to be implemented in many small institutions. To accommodate these needs and help the Greek institutions contribute their content to Europeana, we developed a series of tools. The Hellenic Aggregator that has established a single communication point with Europeana. The Open Archives Engine (OAE) software for creating digital library aggregators. The oaipmh. com tool for validating OAI-PMH enabled repositories. Other wrappers that enable repeatable generation and harvesting of ESE-compatible metadata via OAI-PMH. We present these tools and the way that helped the Greek cultural institutions in contributing content to Europeana.

Ethics for Europeana: Council of Content Providers & Aggregators

Malliet, J., Ugricic, S., Brungs, J., Cousins, J. & Koulouris A. (2011)
Position Paper

Europeana is not generally associated with ethics. Its core business is about access to cultural heritage, internet technology and support for digitisation. It is a strictly European initiative, a collaborative effort among many kinds of memory institutions from all over Europe. The data and information contained in the Europeana database and presented to users worldwide is not compiled by or for Europeana. It is collected from a large number of contributing cultural memory institutions and was produced for many different purposes. It originated in a huge variety of contexts.

Implementing enhanced OAI-PMH requirements for Europeana

Houssos, N., Stamatis, K., Banos, V., Kapidakis, S., Garoufallou, E., & Koulouris, A. 2011)
Conference Paper In S. Gradmann et al. (Ed.), Proceedings of the International Conference on Theory and Practice of Digital Libraries (TPDL 2011), Berlin, Germany, September 25-29, 2011, Lectures Notes in Computer Science (LNCS), vol. 6966, pp. 396-407. Berlin Heidelberg: Springer-Verlag.

Europeana has put in a stretch many known procedures in digital libraries, imposing requirements difficult to be implemented in many small institutions, often without dedicated systems support personnel. Although there are freely available open source software platforms that provide most of the commonly needed functionality such as OAI-PMH support, the migration from legacy software may not be easy, possible or desired. Furthermore, advanced requirements like selective harvesting according to complex criteria are not widely supported. To accommodate these needs and help institutions contribute their content to Europeana, we developed a series of tools. For the majority of small content providers that are running DSpace, we developed a DSpace plug-in, to convert and augment the Dublin Core metadata according to Europeana ESE requirements. For sites with different software, incompatible with OAI-PMH, we developed wrappers enabling repeatable generation and harvesting of ESE-compatible metadata via OAI-PMH. In both cases, the system is able to select and harvest only the desired metadata records, according to a variety of configuration criteria of arbitrary complexity. We applied our tools to providers with sophisticated needs, and present the benefits they achieved.

Theses e-submission tool at the National Technical University of Athens

Koulouris, A., & Anagnostopoulos, A. (2010).
Journal Paper OCLC Systems & Services: International Digital Library Perspectives, 26(2), 123-132.

Purpose – This paper's aim it to analyze added value that the theses e-submission system (tool) gave to the NTUA IR service. Design/methodology/approach – The paper describes the e‐submission tool, its procedures and evaluates its use. Findings – The tool improved the IR service, which can be certified by the continuing evaluation process. This process produced the following main results: the automated batch importing feature should be integrated into the e‐submission system; IR service tutorials should be given to the secretariats, faculty and students; and in‐house service marketing should be conducted. Research limitations/implications – The present study provides a starting‐point for further research in DL open source software. Originality/value – The paper shows that the tool helped NTUA users in submitting their e-theses, and the IR staff in organizing efficiently the service workflow and the data integration into the DSpace system. The process weaknesses rectifications will enhanse the service and allow its broadness to all NTUA departments. This tool implementation may start a debate to the DSpace community in using proxies between DSpace platform and the end user, as an alternative.

Visualizing negotiation communications in setting library sharing policies

Journal Paper International Journal of Applied Systemic Studies (IJASS), 3(4), 404-422

Today's libraries provide a broad and diverse range of resources, from books to videos and databases, and sharing conditions for each depend on modality, source, and mode of usage. In this paper, we introduce and discuss a flexible, semi-automated mechanism to assist in setting policies and tracking their implementation based on the Secure Content Exchange Negotiation System (SCENS). We consider how SCENS can be extended and applied to libraries, including as a tool for reconciling multi-institutional or multi-national policies. We also show how monitoring of SCENS negotiations can help set library sharing policies and resolve future conflicts by tracking the evolution of sharing agreements.

Conference Paper Proceedings of the 19th Hellenic Academic Libraries Conference, Athens, Greece, November 3-5, 2010, pp. 87-105.

This presentation concerns pragmatic approaches on achieving interoperability in digital libraries and repositories based on relevant experiences of the authors in real-life, large scale, successful use cases such as: (a) the establishment – within the EuropeanaLocal project – of a national aggregator, harvesting digital content (more than 170000 records) from various repositories across the country to incorporate it into Europeana, the single portal / gateway to distributed European cultural heritage resources developed as an initiative of the European Commission, (b) the development and operation of openarchives.gr, a single, unified search engine over Greek digital libraries and repositories that currently indexes metadata from 39 systems (more than 340000 records) and (c) the inclusion of content (roughly 40000 items) from disparate data sources to Pandektis, a thematic repository of cultural heritage and humanities material and Helios – the institutional repository of the National Hellenic Research Foundation.

Automated metadata harvesting among Greek repositories in the framework of EuropeanaLocal: dealing with interoperability

EuropeanaLocal is a best practice network project, which will help Europeana to enhance its content and service by applying automated metadata harvesting among distributed repositories. Greek content providers and its metadata aggregator, the Veria Central Public Library (VCPL), are in a testing metadata harvesting period, in the framework of EuropeanaLocal. This paper analyzes the practices that the Greek Institutional Repositories follow in order to transform their metadata schemas to European Semantic Elements (ESE) profile and to export this profile through OAI-PMH to the VCPL aggregator. In addition, it describes the way in which the VCPL aggregates the ESE exported metadata output. Finally, it emphasizes on the transformation and aggregation tools that have been launched on a local level, before Europeana disseminates its official ones.

This paper presents the EuropeanaLocal project, funded by the European Commission that aims to assist cultural repositories to provide access to digital content that they hold to Europeana, the European Digital Library. The paper emphasizes at the effort of Greek Institutional Repositories to provide cultural content to Europeana via their involvement at the EuropeanaLocal project. Greek libraries, museums and archives content providers trying to adopt interoperability standards, the automated metadata harvesting model of Europeana, enrich their metadata by applying the European Semantic Elements metadata schemas in order to be able to migrate their metadata and make available their content of immense value to Europeana. Finally, the paper analyzes the results of a research conducted in Greek repositories participating in the project, which demonstrates their readiness for this project, problems encountered, the diversity of materials and standards that they are used, etc. Finally, the paper illustrates the growing opportunities arise for libraries and other cultural institutions (archives, museums) through their participation in the EuropeanLocal Project.

Οι βιβλιοθήκες τέχνης διαδραματίζουν σημαντικό ρόλο συμβάλλοντας στη διατήρηση, ανάδειξη και διάδοση της πολιτιστικής κληρονομιάς. Στη συστηματική προσπάθεια ψηφιοποίησης και διάθεσης των πολιτιστικών τεκμηρίων που συντελείται τα τελευταία χρόνια, οι ελληνικές βιβλιοθήκες τέχνης υστερούν κυρίως στη δημιουργία αποθετηρίων, στην προσπάθεια μαζικών ψηφιοποιήσεων και τεκμηρίωσης του ψηφιακού υλικού τους. Η εργασία αυτή παρουσιάζει τους τρόπους με τους οποίους οι βιβλιοθήκες τέχνης μπορούν να ψηφιοποιήσουν το υλικό τους και να το κάνουν διαθέσιμο μέσω ενός αποθετηρίου στο ευρύ κοινό. Επίσης, αναλύει θέματα όπως, πρότυπα και διαλειτουργικότητα μεταδεδομένων, αυτόματη συγκομιδή μεταδεδομένων, μετανάστευση μεταδεδομένων στη Europeana, κ.α. Τέλος, περιγράφει πώς το Ευρωπαϊκό Πρόγραμμα EuropeanaLocal σκοπεύει να κάνει εύκολα και άμεσα διαθέσιμο το ψηφιακό περιεχόμενο τοπικής αξίας και ενδιαφέροντος από κατανεμημένα ελληνικά αποθετήρια βιβλιοθηκών τέχνης στη Europeana, την Ευρωπαϊκή Ψηφιακή Βιβλιοθήκη.

There is a trend in cultural organizations, such as, libraries, museums, archives, to digitize or to make available via the Web digitally born content, which turns to be vital for them. However, this mass digital production arise interoperability issues on metadata schemes, harvesting, protocols and systems and other critical points like access, intellectual property and preservation. In this context, Europeana is developing a common multilingual access point, which will make it possible to search Europe’s distributed digital cultural heritage online. The Europeana service tries to manage this cultural heritage content by applying automated metadata harvesting model in a range of distributed repositories. This effort is enhanced by the best practice network project EuropeanaLocal, which will help local and regional libraries, museums, archives and audio-visual archives to make the enormous amount of content that they hold available through Europeana and deliver new services. This paper analyzes the cultural heritage management prototype within Europeana and EuropeanaLocal framework. Finally, it emphasizes, as a case study, on the effort that the Greek cultural content repositories make to incorporate the Europeana’s standards, in order to provide Europeana service with cultural heritage content metadata through OAI-PMH automated harvesting procedure.

Conference Paper Proceedings of the 11th International Symposium on Electronic Theses and Dissertations (ETD 2008), Aberdeen, Scotland, United Kingdom, June 4-7, 2008

The National Technical University of Athens (NTUA), through its Central Library, offers an Institutional Repository (IR) and ETD submission service, currently operating in a pilot testing period. The main objectives of this paper can be summarized into three major points. Primarily, to evaluate the IR service pilot period, focusing on the ETD submission process. Secondarily, to refine and improve the above mentioned process and, finally, to promote the concept of selfarchiving and open access. The project was undertaken by implementing a web-based survey, targeting on the ETD submission users’ population. The data were imported into and processed by statistical analysis software. The key results were exposed online, as part of the IR system, updated in real time, since the survey is an ongoing procedure. The statistical analysis produced useful results regarding various aspects of the IR service. The major descriptive statistics focused on user groups, administrative staff and procedure grading, as well as access policy selection. Moreover, cross tabulations and correlations were created between all variables, for example “university department” and/or “ETD type” associated with “access policy”. A positive user attitude towards the procedure was noted, which motivates us to further enhance and expand the service. Our first milestone is to broaden the service to incorporate all the university departments. For that to happen, the statistical results will be used to forecast, define and, finally, determine the process needs, both in technical and human resources terms. Process weaknesses detected will be rectified, wherever possible, whereas process strengths will be used to market the service. At the same time, certain improvements, such as the transition from a semi-automated metadata importing process into the main IR (DSpace), to a fully automated one (batch), are already in development.

Conference Paper Proceedings of the 17th Hellenic Academic Libraries Conference, Ioannina, Greece, September 24-26, 2008

The NTUA Central Library offers an Institutional Repository (IR) service combined with an ETD e-submission system. The e-submission system developed from scratch by library staff members currently operates in a pilot period. This paper’s main objectives are: a) the IR service pilot period evaluation, focusing on the e-submission process, b) the service capacity evaluation, both in technical and human resources terms, c) the service improvement and broadness to all university departments and, finally, d) the self-archiving and open access concept promotion. The survey was conducted by means of a web-based questionnaire, on the e-submission users’ population. The key results were posted online, as part of the IR service, and are updated in real time.

Policy Decision Tree for Academic Digital Collections

Conference PaperIn L. Kovacs, N. Fuhr, & C. Meghini (Eds.), Proceedings of the 11th European Conference on Research and Advanced Technology for Digital Libraries (ECDL 2007), Budapest, Hungary, September 16-21, 2007, Lectures Notes in Computer Science (LNCS), vol. 4675, pp. 481-484. Berlin Heidelberg: Springer-Verlag.

We present the results of a questionnaire survey for the access and reproduction policies of 67 digital collections in 34 libraries (national, academic, public, special etc) from 13 countries. We examine and analyze the above policies in relation to specific factors, such as, the acquisition method, copyright ownership, library type (national, academic, etc.), content creation (digitized, born-digital) and content type (audio, video, etc.); how these factors affect the policies of the examined digital collections. Responses were received from a range of library sectors but by far the best responses came from academic libraries, in which we focus. We extract policy (access, reproduction) rules and alternatives according to these factors that lead to a policy decision tree on digital information management for academic libraries. The resulting decision tree is based on a policy model; the model and tree are divided into two parts: for digitized and born-digital content.

The institutional repository of NTUA: challenges, concerns, pilot implementation and perspectives.

Conference Paper Proceedings of the 10th International Symposium on Electronic Theses and Dissertations (ETD 2007), Uppsala, Sweden, June 13-16, 2007.

This paper describes the challenge, development and pilot implementation of the Institutional Repository (IR) at the National Technical University of Athens (NTUA). It portrays the vision of the Central Library of NTUA, to provide open access to grey literature, in order to promote the scientific research. Our Digital Library (DL) is a DSpace installation, containing unique digitized collections and an evolving IR with ETDs. Our primary goal is to establish new routines to academic community for ETDs, e-submission and self-archiving. We already have the “law”; the relevant decision of the senate that gives us the right to collect-deposit the ETDs and to define the necessary specifications, standards and procedures for writing, e-submission, storage, deposit and access of ETDs. We adhere to the templates that each department has established for ETD writing, however, our prospect is to implement a flexible, integrated and unique template, based on ETD guide. Current progress constitutes the preparation and implementation of a web-based e-submission form for ETDs and its relevant online help (in Greek and English); the necessary modification and addition of Dublin Core (DC) metadata fields for ETDs DC registry; and the policies for, metadata storage and accessibility, copyright ownership and access of ETDs. We have two access points for ETDs, the library’s OPAC and the DSpace system, for interoperability, metadata preservation, and integration reasons. Additionally, modifications have been made to the DSpace web interface for satisfying our user-centered needs. Finally, the appropriate metadata, copyright and access policy documentation is available on our website and is analyzed. Current steps include the formal promotion of ETDs and e-submission procedure, and the evaluation of the pilot testing period (approximately six months) of IR. Future plans: personalization, integration of DL collections and services, submission of modifications to the DSpace development community; participation in NDLTD Union Catalogue and movement.

Digital library and institutional repository development at NTUA Central Library

Conference PaperIn Proceedings of the 16th Hellenic Academic Libraries Conference, Piraeus, Greece, October 1-3, 2007, pp. 378-392

This paper describes the Digital Library (DL) and Institutional Repository (IR) development at the National Technical University of Athens (NTUA). The project is co-funded by the European Social Fund (75%) and National Resources (25%) – (EPEAEK II). Our DL is a DSpace installation, containing unique digitized collections and an evolving IR with Electronic Theses and Dissertations (ETDs). On the one hand, the Central Library tries to promote the Greek cultural heritage, by providing unique digitized content. Current digitization includes two unique in Balkans Greek journal titles, Archimedes and Prometheus, and approximately 800 rare books, part of the Scientific and Technical Greek Bibliography (1830-1940). This digitized collection, aims to facilitate the researchers in science and technology history field. On the other hand, the IR, for the time being, deposits only NTUA ETDs. However, plans include the deposition and preservation of the grey literature’s bulk (research papers, etc.), produced at NTUA. Our primary goal is to establish new routines for the academic community regarding ETDs, e-submission and self-archiving. We already have the NTUA Senate’s decision that gives us the right to collect-deposit the ETDs and the responsibility to define the necessary specifications, standards and procedures for writing, e-submission, storage, deposit and access of ETDs. We adhere to the existing ETD templates that each faculty has established, however, our prospect is to implement a flexible, integrated and unique template, based on the UNESCO ETD guide. So far, progress has been achieved in preparing and implementing a web-based e-submission form for ETDs and its relevant online help in Greek and English; modifying and adding the necessary Dublin Core (DC) metadata fields for ETDs DC registry; designing and implementing the policies for metadata storage and accessibility, and access of ETDs. We have already implemented the e-submission system, a separate web application, acting as a proxy between DSpace and the end user and started our pilot testing period, from June 2007. Additionally, code and GUI modifications have been made to DSpace for satisfying our specific user needs. Current steps include the IR pilot testing period’s evaluation, focusing on the scientific community’s reaction in self-archiving and e-submission. We provide two access points for ETDs, the library’s OPAC and the DSpace system, for interoperability, metadata preservation, and integration reasons. The authors submit the policy statement in which they define the access policy they prefer (i.e. WWW access, NTUA access and no access), and afterwards, the ETDs’ metadata and full text. The implemented access policies are user-centered and based on international standards and practices (i.e. NDLTD). Future plans include, but are not limited to, personalization, integration of DL collections and services, full-text searching capability, implementation of the federated searching feature to all heterogeneous resources (DL collections, IR, OPAC, etc.), automated batch importing of metadata to the DSpace system, submission of code and GUI modifications to the DSpace development community; participation in NDLTD Union Catalogue and movement.

Digital library content access and distribution policies

Alexandros Koulouris (2007)
PhD Thesis. Corfu: Ionian University

In this PhD thesis, the access and availability policies (policies from now on) of libraries’ digital content are examined in relation to specific factors, which according to bibliography, affect them. The factors refer to acquisition method, intellectual property, content type, digital content creation type and library type. The intellectual property and policies relation is examined in different countries worldwide. The electronic theses and dissertations, is the case study selected for analyzing the relation of policies and content type. Alternative access policies for such content are proposed. The national and academic libraries worldwide, is the core for the policies and library type’s relation analysis. The questionnaire, the personal observation and the study of the relevant literature are the methods used for collecting the research data. Generalized rules in relation to the factors are extracted for the libraries’ followed policy practices. The absence of an appropriate model for national and academic libraries’ digital content is ascertained. Two flexible access and reproduction policy models for national and academic libraries’ digital content are proposed. The models contain simplified policy rules, resulted from libraries’ common policy practices, supplemented by alternative policy proposals. Each model results in a decision tree, which proposes alterative and flexible access and reproduction policy routes according to the factors, digital content creation type, acquisition method and intellectual property that apply on each case. The proposing policy models and the decision trees that result in, hope to be helpful in resolving the policy problem. Additionally, they may constitute useful tools (guides) in forming the policies and managing the national and academic libraries’ digital information (content).

Access and reproduction policies of university digital collections

Koulouris, A., & Kapidakis, S. (2005)
Journal Paper Journal of Librarianship and Information Science, 37(1), 25-33.

The access and reproduction policies of the digital collections of 10 leading university digital libraries worldwide are classified according to factors such as the creation type of the material, acquisition method, copyright ownership etc. The relationship of these factors is analysed, showing how acquisition methods and copyright ownership affect the access and reproduction policies of digital collections. The article concludes with rules about which factors lead to specific policies. For example, when the library has the copyright of the material, reproduction for private use is usually provided free with a credit to the source or otherwise mostly under fair use provisions, but commercial reproduction needs written permission and fees are charged. Finally, common practice on access and reproduction policies are extracted and conventional policies are mapped onto digital policies.

Applying library policies for digital content access to the commercial sector

The digital content of libraries is different from commercial digital products, such as, computer applications, software tools, and computer code or data streams, but they have the same sharing, reproduction and distribution digital properties and similar knowledge management problems. We examine the policies applied to commercial and library digital content. We classify the commercial digital products, according to their use and distribution properties, and we analyze their policy components. Mapping on library and commercial sector policies is illustrated, and their similarities and differences are extracted. Within this mapping, we conclude by showing, how a subset of the library policies can be transferred and implemented by companies. We show how this implementation could be beneficial for commercial companies, because libraries have great experience in providing digital content and in implementing policies. In this sense, libraries are leading the way, by showing to commercial companies how to handle and provide digital content.

Berlin Heidelberg: Springer-Verlag.

The access and reproduction policies of the digital collections of ten leading university digital libraries worldwide are classified according to factors such as the creation type of the material, acquisition method, copyright ownership etc. The relationship of these factors is analyzed, showing how acquisition methods and copyright ownership affect the access and reproduction policies of digital collections. We conclude with rules about which factors lead to specific policies. For example, when the library has the copyright of the material, the reproduction for private use is usually provided free with a credit to the source or otherwise mostly under fair use provisions, but the commercial reproduction needs written permission and fees are charged. The extracted rules, which show the common practice on access and reproduction policies, constitute the policy model. Finally, conventional policies are mapped onto digital policies.

Visualizing negotiation communications in setting library sharing policies

Ford, J., Zhao, Y., Ye, S., Zhang, S., Makedon, F., Le, Z., Koulouris, A., & Kapidakis, S. (2005).
Conference Paper In Proceedings of the 1st Hellenic Society for Systemic Studies National Conference 2005 (HSSS 2005), in co-ordination with the University of Peloponnese, Tripolis, Greece, May 12-14, 2005, pp. 192-208

Today's libraries provide a broad and diverse range of resources, from books to videos and databases, and sharing conditions for each depend on modality, source, and mode of usage. In this paper, we introduce and discuss a flexible, semi-automated mechanism to assist in setting policies and tracking their implementation based on the Secure Content Exchange Negotiation System (SCENS). We consider how SCENS can be extended and applied to libraries, including as a tool for reconciling multi-institutional or multi-national policies. We also show how monitoring of SCENS negotiations can help set library sharing policies and resolve future conflicts by tracking the evolution of sharing agreements.

Conference PaperIn Proceedings of the 14th Hellenic Academic Libraries Conference, Neo Faliro, Greece, December 1-3, 2005, pp. 227-238

Conventional policies do not map directly, but indirectly, onto digital ones with differences primarily due to the easy duplication properties of the digital content. We examine the functional linkage on conventional and digital policies of access, reproduction, library loan and inter-library loan. We map and compare the conventional to digital policies on the collections (conventional and digital) of ten leading academic libraries worldwide, showing their similarities, differences, advantages and disadvantages. We answer questions, such as, if the digital policies are transformation of conventional ones or they are new cases, if they are more liberal than conventional or restricted etc. Finally, we propose a policy model of access, reproduction and use for the digital content of academic libraries, according to factors, such as, the content creation type, acquisition method, intellectual property etc. The model, integrates already implemented practices, but also new policies that have not been implemented so far, and can offer solutions to the management of digital information and knowledge.

Policy Model for National and Academic Digital Collection

The access and reproduction policies of the digital collections of fifteen leading academic and national digital libraries worldwide are classified according to factors such as the creation type of the material, acquisition method and copyright ownership. The relationship of these factors and policies is analyzed and quantitative remarks are extracted. We propose a policy model for the digital content of the national and academic libraries. The model consists of rules, supplemented by their exceptions, about which factors lead to specific policies. We derive new policy rules on access and reproduction when different copyright terms are applied. We conclude with findings on policies. Finally, we compare national and academic library policies, showing interesting results that arise on their similarities and differences.

Knowledge Management Policies on Digital Content of Libraries

Koulouris, A., & Kapidakis, S. (2005)
Conference PaperIn Proceedings of the 1st Hellenic Society for Systemic Studies National Conference 2005 (HSSS 2005), in co-ordination with the University of Peloponnese, Tripolis, Greece, May 12-14, 2005, pp. 394-407

We analyze the use of the digital content of non-profit libraries, such as, national and academic, worldwide, as expressed through the restrictions of intellectual property and the knowledge management policies. We classify the policies according to factors, such as, the content creation type, its acquisition method and intellectual property, analyze their relationship and extract quantitative remarks. We propose a policy model of access, reproduction and use for the digital content of national and academic libraries. The model contains not only library implemented practices, but also, new, and not implemented so far, policies, which can offer solutions to management of digital information and knowledge; in addition, rules on policies supplemented by their exceptions. Two separate policy models, for the digitized and the born-digital, arise and presented respectively, and relevant conclusions that valid on each case are extracted. Finally, findings on policies, common, for national and academic libraries, and unique, are presented.

Considerations on Policies of University Digital Collections

Conference Paper Proceedings of the 6th Russian Conference on Digital Libraries (RCDL 2004), Pushchino, Russia, September 29-October 1, 2004, pp. 159-168.

We examine the factors (creation type of the material, acquisition method, copyrightownership etc.) and the access and reproduction policies of the digital collections of ten leading university digital libraries. We classify the policies according to the factors and analyze their relation, showing how the acquisition method and the copyright ownership define the access and reproduction policies for the digital collections. We conclude with rules about which factors lead to specific policies. For example, when the library has the copyright of the material, the reproduction for private use is provided usually free with a credit to the source or otherwise mostly under fair use provisions and the commercial reproduction needs written permission from and fees given to the library. Finally, we extract the common practice onaccess and reproduction policies and we map the conventional to digital policies.

Policies for academic digital collections

Conference PaperIn Proceedings of the 13th Hellenic Academic Libraries Conference, Corfu, Greece, October 13-15, 2004, pp. 499-512

We examine and classify the access and reproduction policies of the digital collections of ten leading academic digital libraries according to factors such as the creation type of the material (digitized, born-digital), the acquisition method, the copyright ownership etc. We analyze the relationship of the factors and the policies, showing how the acquisition method and the copyright ownership affect the access and reproduction policies for the digital collections. We derive some quantitative remarks and we conclude with rules about which factors lead to specific policies. For example, when the library has the copyright of the material, the reproduction for private use is provided usually free with a credit to the source or otherwise mostly under fair use provisions and the commercial reproduction needs written permission from and fees given to the library. We extract the common practice on access and reproduction policies. For example, the on-campus onsite access is always free independently of the copyright ownership and the creation type of the material. Finally, we map the conventional access and reproduction policies to digital and we compare them, showing mostly their differences.

Access and reproduction policies of the digital material of seven national libraries.

Koulouris, A., & Kapidakis, S. (2003)
Conference Paper In Proceedings of the 5th Russian Conference on Digital Libraries (RCDL 2003), Saint-Petersburg, Russia, October 29-31, 2003, pp. 35-44

In this paper, we examine the access and reproduction policies of the digital material of seven National Libraries. The selection of the examined National Libraries is based on the variation of their digital content and the diversification of their access policies. Our goal is to discover the differences among the implemented access policies of these National Libraries. We analyze the access and reproduction policies that these libraries have implemented for their digital material showing the different levels of access, the copyrights, the privacy and publicity rights. We also mention the acquisition policies, because, often, the access and the reproduction policies are related to the way that the library has acquired the material and the status of its copyright ownership. When the digital content (text, image, audio, video etc.), does not have restrictions (copyright, privacy and publicity rights limitations, distribution restrictions etc.), then the most common access policy is the “free access”. Otherwise, when the digital material has restrictions, then the access policy is restricted for onsite users only and the reproduction requires written permission or fees. The implemented access policies differ in various aspects. We generalize them into one unified policy, which can implement the specific policies by varying some of its parameters. We study these parameters and explain their most useful alternative values and their semantics. We also foresee new policy parameters that will be appropriate to more complex policies that will be needed soon.

Collections and access policies of the digital material of ten national libraries

Koulouris, A., Kapidakis, S., & Zhao, Y. (2003)
Conference Paper Proceedings of the 3rd ACM/IEEE-CS Joint Conference on Digital Libraries (JCDL 2003), Houston, Texas, USA, May 27-31, 2003, p. 409. Washington: IEEE Computer Society.

We explore the digital collections of ten National Libraries and the applied access policies, when the digital material is free or restricted or the reproduction requires written permission or fees. We classify the implemented access policies according to their characteristics. We examine the differences among the implemented access policies and we generalize the solution approaches combining the varying parameters and other relevant emerging ones. The selection of the access policies is crucial for the acceptance and maintenance of the digital libraries. The success of any conventional or digital library depends on the usage of its material from the users. The usage of the material depends on the selection of the access policy.

Writing and submission specifications of electronic theses and dissertations.

The grey literature, including the theses and dissertations, comprises a special form of unpublished material and its knowledge is essential for the whole academic and research community. However, few people know the existence of the printed grey literature. The access to the printed grey literature is not easy, even to the people that know its existence. However, there are efforts to collect the grey literature, such as the collection of the dissertations at the NDC or other university efforts, in which the grey literature is widely known, especially when it is accessible electronically. In the international scientific community, there are initiatives to deposit, collect and provide the grey literature electronically. The Electronic Theses and Dissertations (ETDs) is the most important initiative. This initiative started at Virginia Tech, which is the first university that demanded electronic submission of ETDs, and evolved in a Networked Digital Library of Theses and Dissertations (NDLTD) of 183 members (159 Universities and 24 Institutions) from all over the world. This digital library is a Union Catalogue of ETDs linked with the full text. The electronic submission and provision of the ETDs benefit from the use of appropriate specifications for writing and deposition. A very important initiative on this matter is the UNESCO Guide for Creating Electronic Theses and Dissertations. This guide contains unified writing and deposition specifications of ETDs. All the universities that participate in the NDLTD or others that have ETDs will apply these specifications. The eventual goal of this guide is to make all students at all universities to be able to create ETDs, with similar layout and structure of their content, in order to have the ETDs easier retrievable and accessible, independently of their creating environment. In addition, this guide enhances the quality of the electronic content and helps the dissemination of the grey literature. We analyze the main points of the UNESCO Guide - where academic libraries should help its implementation - showing how it can help universities to develop their local infrastructure regarding electronic publishing and digital libraries. This guide can be an important tool for the bibliographic control of the electronic content. In addition, it can promote the diffusion of knowledge of the grey literature and the collaboration of universities spanning across all countries and borders. The ultimate effect may be the creation of a universal sustainable program for diffusion of knowledge, across all fields, including science, technology and culture. Finally, this guide could activate procedures for the creation and the electronic submission of the grey literature in Greek universities.

Three Disposition Policies of Electronic Theses and Dissertations

Koulouris, A., & Kapidakis, S. (2003)
Conference Paper In Proceedings of the 6th International Symposium on Electronic Theses and Dissertations (ETD 2003), Berlin, Germany, May 21-24, 2003, pp. 84-90.

We examine the disposition policies of Electronic Theses and Dissertations (ETDs) among three institutions: National Documentation Centre of Greece (NDC), Virginia Tech (VT) and West Virginia University (WVU) of USA. In addition, we compare the implemented disposition policies by the three institutions, and we analyze their similarities and differences. We select the three institutions because they comprise a representative sample of different national ETD initiatives. While the content of the dissertations and the technologies to provide them exist, the availability is limited by the absence of decisions concerning the applicability of policies. We suggest alternative access policies in order the ETDs to be more open and accessible to all. We analyze these questions and make suggestions about the solution approaches of these problems, especially solutions about the disposition policies of the digital material. Finally, we compare the implemented and the proposed policies.

The evolution of the bibliographic database of the Hellenic National Archive of Dissertations of the National Documentation Centre of Greece to digital library

Koulouris, A., & Kapidakis, S. (2002)
Conference PaperIn Proceedings of the 11th Hellenic Academic Libraries Conference, Larissa, Greece, November 6-8, 2002, pp. 121-133.

The scope of this work is to show the evolution of the bibliographic database of the Hellenic National Archive of Theses of the National Documentation Centre to digital library. We make a throwback and evaluation of the project and the evolution of the library with respect to the new technologies. During this process, we highlight the problems, questions that emerge to the new digital reality and also the prospects of the evolution and development of the project. The National Documentation Centre (NDC), is the suitable organization by the law 1566/1985 for collecting the theses that have been elaborated by the Greek researchers in Creek Universities and the theses that have been elaborated by the Creek researchers in Foreign Universities. In 1986, in conjunction with the creation of the archive in printed form, the bibliographic database of the Hellenic National Archive of Theses was also created. The software that have been used for this purpose was the (ABEKT - third edition) and the equipment that was responsible for the provision of the database was the mainframe computer "Hermes" that started working for the first time as a provider of electronic information in 1986. "Hermes " worked with success from 1986 until 1999. The big innovation starts when the NDC decides, in order to have better services for the researchers and the users, to digitize the collection of the theses. The project starts in July 1998 and finishes in December 1999. This is the time for the big changes. The software ABEKT is in the fifth edition and works in Windows environment, implements UNIMARC, UNIMARC Authorities and ISO 2709. It is the time when "Hermes" is abolished and all the bibliographic databases of the NDC are provided with the protocol 119.50. The bibliographic database of the theses constitutes now a WEB database linked with the full text of the theses so we have a digital library of theses (2.000.000 digitized pages and that was the biggest project in Europe at that time). At this new stage we have various problems such as the security of the network and the security of the digital material, the control of the access to the digital content and also the selection of policy or policies concerning the availability of the digital content, questions that demand further investigation. Specifically, while the content of the theses and the technologies to provide them exist, the availability is limited by the absence of decisions concerning the use of policies. We will suggest some alternatives policies taking into account some criteria about the policies: • To be acceptable from all the people (Researchers, Universities, NDC e.g.). • To conform to the current legislation. • To be compatible with the common practice. We will try to analyze these questions and to make suggestions about the solutions of these problems, especially solutions about the policies concerning the availability of the digital material.
