    This report updates and expands on A Survey of Digital Library Aggregation Services, originally commissioned by the DLF as an internal report in summer 2003, and released to the public later that year. It highlights major developments affecting the ecosystem of scholarly communications and digital libraries since the last survey and provides an analysis of OAI implementation demographics, based on a comparative review of repository registries and cross-archive search services. Secondly, it reviews the state-of-practice for a cohort of digital library aggregation services, grouping them in the context of the problem space to which they most closely adhere. Based in part on responses collected in fall 2005 from an online survey distributed to the original core services, the report investigates the purpose, function and challenges of next-generation aggregation services. On a case-by-case basis, the advances in each service are of interest in isolation from each other, but the report also attempts to situate these services in a larger context and to understand how they fit into a multi-dimensional and interdependent ecosystem supporting the worldwide community of scholars. Finally, the report summarizes the contributions of these services thus far and identifies obstacles requiring further attention to realize the goal of an open, distributed digital library system

    A Survey of Digital Library Aggregation Services

    This report provides an overview of a diverse set of more than thirty digital library aggregation services, organizes them into functional clusters, and then evaluates them more fully from the perspective of an informed user. Most of the services under review rely wholly or partially on the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH), although some of them predate its inception and a few use predominantly Z39.50 protocols. In the opening section of this report, each service is annotated with its organizational affiliation, subject coverage, function, audience, status, and size. Critical issues surrounding each of these elements are presented in order to provide the reader with an appreciation of the nuances inherent in seemingly straightforward factual information, such as audience or size. Each service is then grouped into one of five functional clusters: • open access e-print archives and servers; • cross-archive search services and aggregators; • from digital collections to digital library environments; • from peer-reviewed referratories to portal services; • specialized search engines

    Open Access Publishing and Scholarly Communication Among Greek Biomedical Scientists

    urpose: The purpose of this research is to study in what ways the open access publishing can improve the scholarly communtication among biomedical sciences in Greece over a period of about five years and provide new roles for health librarians to support open access.\ud Methods: The implementation of Critical Realism as research philosophy allowed the multi-level analysis of the research object; a mixture of research tools were used. Supplementary research methods were adopted to provide more accurate and reliable conclusions. The Literature review contributed to the identification of the open access publishing context and the relations which were forming and re-forming in it. Additionally, similar studies were found and the research gaps were identified as well. Bibliometrics demonstrated the participation of Greek scientists in world research could be evaluated. The research was conducted in five world databases (PUBMED, SCI, BIOMED CENTRAL, DOAJ, GOOGLE) for two different periods (2006-2007 and 2011). Publishers? aggrements provided information about the role of Greek biomedical publishers to the awareness of Greek biomedical scientists on journal related issues such as copyright. Additionally, and journal cost analysis presented publishers? subscription and open access policies and provided an approach of the costs requested for the access to journals. Web 2.0 offers new scholarly communication channels that seem to be cheaper and effective ones. The participation of Greek biomedical scientists in social networks such as ResearchGate, LinkedIn was analysed to evaluate the trends towards these new information sources. Case study methodology provided the qualitative and quantitative tools to explain the attitudes and awareness of Greek biomedical stakeholders about open access publishing and open access biomedical journals and also helped to the longitudinal study of the changes. A questionnaire survey among biomedical scientists took place in three phases (2007-early in 2010, September 2010 to May 2011). In addition, Greek biomedical publishers were interviewed in January and February 2010 .\ud Findings: The bibliometric findings indicated an increasing participation of Greek scientists and Greek biomedical journals in world research. Greek biomedical scientists also use social networking as a means of scholarly communication. The questionnaire surveys showed that the physicians are the most active researchers and more familiar with the open access publishing concept. However, across all the phases the majority of Greek biomedical scientists seem to be unaware of aspects of publishing in open access journals, although by the third phase more participants seem to be aware. Greek biomedical publishers seem to approve the deposit in repositories, and the self-archiving process under specific terms, because, the publishers? agreements analysis demonstrated, the publishers want to be the copyright holders and information about authors? rights is omitted. Biomedical scientists are confused over copyright. As far as cost analyses are concerned, the journal prices depend on the publisher (commercial or scientific) and the subscriber (the institutional prices are higher than individual ones). The findngs were interpreted according to Roger?s diffusion of innovations theory and Lewin?s force field analysis.\ud Conclusions: Open access seems to be acceptable in Greece but the stakeholders, including libraries, need to co-operate more. Greek academic biomedical libraries can actively reinforce the driving forces and reduce the restraining forces (around copyright, mainly) (Lewin?s Force Field Analysis) in order to move into the ?refreeze stage?. However, institutional repositories do seem to be an innovation that (according to Rogers? theory) will take time to develop

    Based on the information provided by European projects and national initiatives related to multimedia search as well as domains experts that participated in the CHORUS Think-thanks and workshops, this document reports on the state of the art related to multimedia content search from, a technical, and socio-economic perspective. The technical perspective includes an up to date view on content based indexing and retrieval technologies, multimedia search in the context of mobile devices and peer-to-peer networks, and an overview of current evaluation and benchmark inititiatives to measure the performance of multimedia search engines. From a socio-economic perspective we inventorize the impact and legal consequences of these technical advances and point out future directions of research

    Bibliographic Control in the Digital Ecosystem

    Get PDF
    With the contributions of international experts, the book aims to explore the new boundaries of universal bibliographic control. Bibliographic control is radically changing because the bibliographic universe is radically changing: resources, agents, technologies, standards and practices. Among the main topics addressed: library cooperation networks; legal deposit; national bibliographies; new tools and standards (IFLA LRM, RDA, BIBFRAME); authority control and new alliances (Wikidata, Wikibase, Identifiers); new ways of indexing resources (artificial intelligence); institutional repositories; new book supply chain; “discoverability” in the IIIF digital ecosystem; role of thesauri and ontologies in the digital ecosystem; bibliographic control and search engines

    Resource discovery in heterogeneous digital content environments

    The concept of 'resource discovery' is central to our understanding of how users explore, navigate, locate and retrieve information resources. This submission for a PhD by Published Works examines a series of 11 related works which explore topics pertaining to resource discovery, each demonstrating heterogeneity in their digital discovery context. The assembled works are prefaced by nine chapters which seek to review and critically analyse the contribution of each work, as well as provide contextualization within the wider body of research literature. A series of conceptual sub-themes is used to organize and structure the works and the accompanying critical commentary. The thesis first begins by examining issues in distributed discovery contexts by studying collection level metadata (CLM), its application in 'information landscaping' techniques, and its relationship to the efficacy of federated item-level search tools. This research narrative continues but expands in the later works and commentary to consider the application of Knowledge Organization Systems (KOS), particularly within Semantic Web and machine interface contexts, with investigations of semantically aware terminology services in distributed discovery. The necessary modelling of data structures to support resource discovery - and its associated functionalities within digital libraries and repositories - is then considered within the novel context of technology-supported curriculum design repositories, where questions of human-computer interaction (HCI) are also examined. The final works studied as part of the thesis are those which investigate and evaluate the efficacy of open repositories in exposing knowledge commons to resource discovery via web search agents. Through the analysis of the collected works it is possible to identify a unifying theory of resource discovery, with the proposed concept of (meta)data alignment described and presented with a visual model. This analysis assists in the identification of a number of research topics worthy of further research; but it also highlights an incremental transition by the present author, from using research to inform the development of technologies designed to support or facilitate resource discovery, particularly at a 'meta' level, to the application of specific technologies to address resource discovery issues in a local context. Despite this variation the research narrative has remained focussed on topics surrounding resource discovery in heterogeneous digital content environments and is noted as having generated a coherent body of work. Separate chapters are used to consider the methodological approaches adopted in each work and the contribution made to research knowledge and professional practice.The concept of 'resource discovery' is central to our understanding of how users explore, navigate, locate and retrieve information resources.
