Abstract

The digital library is a socio-technical concept of great significance. It redefines the relationships between information providers and intermediaries and, potentially, transforms the way that services are delivered to users. This article, based on a British Library Research & Innovation Centre funded study, reviews current themes and directions in digital library research and scholarship. It locates the digital library in a simple work-oriented framework emphasising its social as well as its systems and informational dimensions. The article highlights differences in understanding of the digital library construct between the library and computer science communities and identifies some critical areas for further research.

Abstract

This chapter considers the continuing relevance of the ideas of browsing, serendipity, information encountering and literature discovery in the context of the information retrieval (IR) environment of 2010, though its scope extends to the ideas in the broader contexts of information seeking and information-related behaviour. It is based around a selective review of the literature since 1990 and reflection and speculation on the results. The central focus is on questions of how the concept of browsing, serendipity and related ideas have changed in the new IR environment of the web and whether, indeed, they are still meaningfull concepts.

Abstract

The concepts of 'information literacy' and 'digital literacy' are described, and reviewed, by way of a literature survey and analysis. Related concepts, including computer literacy, library literacy, network literacy, Internet literacy and hyper-literacy are also discussed, and their relationships elucidated. After a general introduction, the paper begins with the basic concept of 'literacy', which is then expanded to include newer forms of literacy, more suitable for complex information environments. Some of these, for example library, media and computer literacies, are based largely on specific skills, but have some extension beyond them. They lead togeneral concepts, such as information literacy and digital literacy which are based on knowledge, perceptions and attitudes, though reliant on the simpler skills-based literacies

Abstract

Introduction. This short paper proposes that a unified concept of information as a form of self-organized complexity may be equally applicable to the physical, biological and human/social domains. This is seen as the evolutionary emergence of organized complexity in the physical universe, meaning in context in the biological domain, and understanding through knowledge in the human domain. Method.This study is based on analysis of literature from a wide range of disciplines. Conclusions.This perspective allows for the possibility that not only may the library/information sciences be able to draw insights from the natural sciences, but that library and information science research and scholarship may in turn contribute insights to these disciplines, normally thought of as more 'fundamental'.

Abstract

Presents a selective literature review covering the process of browsing as a means of searching for information. References are selected in order to illustrate the major themes and to bring out points which have not been emphasised before. The main points covered in the review include: consideration of browsing as an important, but under rated and little understood, form of information access; the ability in browsing to find analogies, connections, and new lines of thought; the potential of browsings as an ideal technique for accasional or non expert users; the ability to apply browsing to both paper based and computerized information retrieval; and the ability to search for information in a semi-random fashion leading to serendipitous linkage. Concludes that, despite the acknowledges importance of browsing, the increased effort being expended in making computerized systems browsable and the many references to the concept in the computer literature, there is still a lack of real understanding of the basic concepts of the process

Abstract

Purpose - The purpose of this paper is to review the nature of, and rationale for, user expectations in the digital library setting, and ways in which they may best be met and/or managed. Design/methodology/approach - An analysis of the literature, focusing on empirical studies, and bringing out main themes and issues. Findings - User expectations of digital libraries are often unrealistic, usually unrealistically high, mainly due to the ubiquity of the web search engine as an information environment. Expectations differ between user groups. Both meeting and managing expectations have been promoted as a solution; it is likely that a mix of the two will be most effective. More empirical and conceptual studies are needed. Ways of making the nature of digital library collections and their organisation "visible", embedded in a natural way within their interfaces, are desirable. Originality/value - This is the first paper to review the literature of this topic.

Abstract

Purpose - The purpose of the study was to compare an internet search engine, Google, with appropriate library databases and systems, in order to assess the relative value, strengths and weaknesses of the two sorts of system. Design/methodology/approach - A case study approach was used, with detailed analysis and failure checking of results. The performance of the two systems was assessed in terms of coverage, unique records, precision, and quality and accessibility of results. A novel form of relevance assessment, based on the work of Saracevic and others was devised. Findings - Google is superior for coverage and accessibility. Library systems are superior for quality of results. Precision is similar for both systems. Good coverage requires use of both, as both have many unique items. Improving the skills of the searcher is likely to give better results from the library systems, but not from Google. Research limitations/implications - Only four case studies were included. These were limited to the kind of queries likely to be searched by university students. Library resources were limited to those in two UK academic libraries. Only the basic Google web search functionality was used, and only the top ten records examined. Practical implications - The results offer guidance for those providing support and training for use of these retrieval systems, and also provide evidence for debates on the "Google phenomenon". Originality/value - This is one of the few studies which provide evidence on the relative performance of internet search engines and library databases, and the only one to conduct such in-depth case studies. The method for the assessment of relevance is novel.
