This third edition of what has become a classic among textbooks in schools of library and information science (and related programs) has been thoroughly updated to reflect the evolving technological advancements in the field. Focusing on indexing of the subject matter of material, the beginning chapters review the literature and discuss various principles and practices such as exhaustivity or depth of indexing, specificity, checktags, pre- and post-coordinate indexes, and consistency and quality of indexing. Discussions on abstracting cover such concepts as the different types of abstracts, purpose of an abstract, structured versus narrative abstracts, informative versus indicative abstracts, subject slanting, modular abstracts, and writing and evaluating an abstract. Various styles of indexing used in printed publications such as Index Medicus, the Engineering Index, and Chemical Abstracts are illustrated in the text; although the author is quick to note that printed tools are used much less today in favor of their online counterparts. In the online world, indexing has even greater importance in the effort to retrieve relevant data efficiently. Related concepts such as weighted indexing, linking of terms, and relational indicators are discussed as aids to precision. The idiosyncrasies of indexing special formats such as images and sounds and the Internet, as well as the use of computer-generated or automated indexing and abstracting, are also reviewed. The author admits that the Web has become so large and complex that it is beyond the scope of any single book to explain all of its components. He suggests the use of Web-based services such as The Extreme Web Searcher's Internet Handbook News and Updates http://extremesearcher.com/news.html or Search Engine Watch http://searchenginewatch.com to keep current with new developments.

Abstract Algebra: Theory and Applications is an open-source textbook that is designed to teach the principles and theory of abstract algebra to college juniors and seniors in a rigorous manner. Its strengths include a wide range of exercises, both computational and theoretical, plus many non-trivial applications. The first half of the book presents group theory, through the Sylow theorems, with enough material for a semester-long course. The second half is suitable for a second semester and presents rings, integral domains, Boolean algebras, vector spaces, and fields, concluding with Galois Theory.

This book covers all of the major library classification schemes in use in Europe, UK and US; it includes practical exercises to demonstrate their application. Importantly, classifying electronic resources is also discussed. The aim of the book is to demystify a very complex subject, and to provide a sound theoretical underpinning, together with practical advice and development of practical skills. The book fills the gap between more complex theoretical texts and those books with a purely practical approach. Chapters concentrate purely on classification rather than cataloguing and indexing, ensuring a more in-depth coverage of the topic. - Covers the latest Dewey Decimal Classification, 22nd edition - Provides practical advice on which schemes will be most suitable for different types of library collection - Covers classification of electronic resources and taxonomy construction

Based on new research and years of practical experience, this guide presents the basic knowledge necessary to become a professional indexer. Synthesizing the thinking and experience of indexers and abstractors over the years, the book introduces readers to such fundamentals as the nature of information, the organization of information, vocabulary control, types of indexes and abstracts, evaluation of indexing, and the use of computers. A new chapter on indexing and the Internet has been added, as has a chapter that lists Web resources for indexers and abstractors. The work concludes with a discussion of the education, training, and job opportunities of the profession, as well as a look to the future. With its simple but thorough approach, this book provides readers with a broad overview of the professions, processes, and art of indexing and abstracting.

No matter what you want to learn about abstracting or indexing, this guide will help you find out where to learn it. Library professionals, online information designers, abstractor and indexer freelancers, and publishers' staffs can all find courses that suit their needs in the Directory. Included are courses from public, private, and proprietary institutions in the U.S. and Canada.

The fourth edition of this standard student text, Organizing Knowledge, incorporates extensive revisions reflecting the increasing shift towards a networked and digital information environment, and its impact on documents, information, knowledge, users and managers. Offering a broad-based overview of the approaches and tools used in the structuring and dissemination of knowledge, it is written in an accessible style and well illustrated with figures and examples. The book has been structured into three parts and twelve chapters and has been thoroughly updated throughout. Part I discusses the nature, structuring and description of knowledge. Part II, with its five chapters, lies at the core of the book focusing as it does on access to information. Part III explores different types of knowledge organization systems and considers some of the management issues associated with such systems. Each chapter includes learning objectives, a chapter summary and a list of references for further reading. This is a key introductory text for undergraduate and postgraduate students of information management.

Thoroughly revised and expanded to reflect current developments in the field, this text is designed to provide the beginning student of library and information science with an overview of the most important tools for general reference work and the concepts and theory behind today's reference services. The 21 chapters are divided into two parts. The first 11 chapters deal with concepts and theory and are topical. They cover such areas as ethical aspects of reference services, reference interview, the principles and goals of library instruction, bibliographic control and search strategies, training and continuing education for reference staff, the evaluation of reference services, and the management of these services. In many cases, specific applications in different types of libraries are pointed out. Expanded coverage of electronic reference service is provided by two full chapters devoted to basic principles and current trends in this area. A separate chapter covers unique approaches to reference service for special groups. Part 2 describes the general principles and sources for selecting and evaluating reference tools and the principles for building a reference collection. The remaining chapters discuss the characteristics and uses of particular types of reference tools. This new edition describes a greater number of titles of each type as well as the formulation of strategies for the effective use of specific sources or groups of sources. Scenarios in particular library settings conclude each chapter, offering realistic reference questions and appropriate search strategies. Throughout the text, boxes are used to highlight specific issues, concepts and search strategies that underlie contemporary reference services. Selected important sources for further reading are listed at the end of each chapter. This text presents the essential theory and practical knowledge necessary for an initial reference course. Its broad scope and organizational clarity should benefit students and practitioners alike.
