Contains thirteen essays in which attendees at the American Society for Information Science's May 1999 mid-year meeting present a number of perspectives on evaluating networked information services and resources.

This book provides a comprehensive view of the methods and approaches for performance evaluation of computer networks. It offers a clear and logical introduction to the topic, covering both fundamental concepts and practical aspects. It enables the reader to answer a series of questions regarding performance evaluation in modern computer networking scenarios, such as ‘What, where, and when to measure?’, ‘Which time scale is more appropriate for a particular measurement and analysis?’, 'Experimentation, simulation or emulation? Why?’, and ‘How do I best design a sound performance evaluation plan?’. The book includes concrete examples and applications in the important aspects of experimentation, simulation and emulation, and analytical modeling, with strong support from the scientific literature. It enables the identification of common shortcomings and highlights where students, researchers, and engineers should focus to conduct sound performance evaluation. This book is a useful guide to advanced undergraduates and graduate students, network engineers, and researchers who plan and design proper performance evaluation of computer networks and services. Previous knowledge of computer networks concepts, mechanisms, and protocols is assumed. Although the book provides a quick review on applied statistics in computer networking, familiarity with basic statistics is an asset. It is suitable for advanced courses on computer networking as well as for more specific courses as a secondary textbook.

Provides update to current thinking about, and reasons for, service evaluation of libraries in the UK. Examines quantitative and qualitative methods including questionnaires, focus groups, suggestions boxes and interview techniques.Problems arising from survey outcomes are summarised and long-term evaluation and the relevance of benchmarking are discussed.Contains case studies covering survey work in public, academic and special libraries; charters and service level agreements; and examples of relevant research projects.New chapter on performance measurement in the electronic library.

Historical Information Science is an extensive review and bibliographic essay, backed by almost 6,000 citations, detailing developments in information technology since the advent of personal computers and the convergence of several social science and humanities disciplines in historical computing. Its focus is on the access, preservation, and analysis of historical information (primarily in electronic form) and the relationships between new methodology and instructional media, techniques, and research trends in library special collections, digital libraries, data archives, and museums.

Information representation and retrieval : an overview -- Information representation I : basic approaches -- Information representation II : other related topics -- Language in information representation and retrieval -- Retrieval techniques and query representation -- Retrieval approaches -- Information retrieval models -- Information retrieval systems -- Retrieval of information unique in content or format -- The user dimension in information representation and retrieval -- Evaluation of information representation and retrieval -- Artificial intelligence in information representation and retrieval.

Applicable for all types of libraries. Needs assessment can be defined as the process of using one or more techniques to collect and analyze data on library users or potential users. The guide includes the methodology and techniques for carrying out needs assessment projects, ranging from short-term assessments to long-term research or comprehensive collection assessments. Various types of data, techniques, and methodology are described, as are associated pointers and pitfalls.

As information service management becomes increasingly critical in the 1980s, its attention is no longer limited to the acquisition, indexing, and storage of documents. Instead, it is taking on an expanded role in the understanding and analysis of economic issues and the management of technological innovation, This collection defines the dimensions of this expanded role and suggests strategies for improved information service management. Three principal areas related to information policy and decision making are covered: economics and government policy, management and marketing of services, and innovations and the impacts of technology. The book provides a practical and comprehensive background and framework for librarians, students of information science, information center managers, and others who are concerned with effective management of information services.

Bringing together library and information science faculty and practicing library managers, this work combines some of the most exciting concepts and methodologies of library evaluation with the practical experiences of those working in the field. A variety of approaches (e.g., focus groups, TQM) are thoroughly described, then illustrated with actual case studies. These cases can serve as inspiration and models to library managers and other individuals responsible for evaluation, as well as to those who aspire to library management positions.

Digital Libraries: Policy, Planning and Practice brings together a wealth of international experience in the planning and implementation of digital and hybrid library projects, providing a stimulating and informative handbook and reference for library staff and information managers. It consists of chapters contributed by leading specialists from Europe, North America, South Africa and the Middle East, who offer their insight into the decision-making processes that have shaped a variety of different digitization programmes. Beginning with introductory overviews of the digital library context, the US Digital Library Program and the UK e-lib and hybrid library programmes, Digital Libraries then divides into two main sections on policy and planning, and implementation and practice. The first explores concerns such as financial and resource planning, digitized compared to born-digital content and related service issues, open access to scholarly research archives, policies for and against preservation and their justification, and evaluating electronic information services. The second section is based on case studies on major European and North American digital library projects, including the Glasgow Digital Library, UCEEL (University of Central England Electronic Library), the Networked Digital Library of Theses and Dissertations (discussed in the context of five international projects), the Indiana University music Variations and Variations2 Project, and the beginnings of the Library of Congress digital program and its integration into core library services. The concluding chapter discusses the way forward for digital libraries in the context of experiences at Tilburg University library, and possible enabling or limiting factors in the future. The result of drawing together these varied and illuminating experiences is a book that offers useful information and comparisons for all digital library project staff, institutional administrators, educators and developers of learning technology. It also provides useful pointers for researchers and project staff involved in archive and museum projects, as well as introducing students to the key ingredients of successful digital libraries.
