Abstract

This revised edition of Wynar's Introduction to Cataloging and Classification (9th ed., 2000) completely incorporates revisions of AACR2, enhancements to MARC 21, and developments in areas such as resource description and access. Aside from the many revisions and updates and improved organization, the basic content remains the same. Beginning with an introduction to cataloging, cataloging rules, and MARC format, the book then turns to its largest section, "Description and Access." Authority control is explained, and the various methods of subject access are described in detail. Finally, administrative issues, including catalog management, are discussed. The glossary, source notes, suggested reading, and selected bibliography have been updated and expanded, as has the index. The examples throughout help to illustrate rules and concepts, and most MARC record examples are now shown in OCLC's Connexion format. This is an invaluable resource for cataloging students and beginning catalogers as well as a handy reference tool for more experienced catalogers.

Abstract

This being the Birth Centenary.Year of Dr. S. R. Ranganathan, it was deemed as a befitting tribute to the author of Colon Classifiction to bring together all that has been published thus far on it and complile it in the form of a bibliographies are an important source of information on a particular field of study and research. A research worker has to carry out the literature survey on the area of interest which sometimes consumes many precious man hours in order to collect some relevent citations. Thus bibliographies are a useful source in saving the precious time and energy of the reseach workers, and lead them to the primary sources for carryying out the research further to the destination.

Abstract

This is a practical tool and comprehensive introduction to the use of controlled vocabularies. This authoritative and detailed volume presents readers with a 'how-to' guide to building controlled vocabulary tools, cataloguing and indexing cultural materials with terms and names from controlled vocabularies, and how to use vocabularies in search engines and databases to enhance discovery and retrieval online. "Introduction to Controlled Vocabularies" also features in-depth discussions on a number of topics, including: What are controlled vocabularies and why are they useful? Which vocabularies exist for cataloguing art and cultural objects? and how should they be used for indexing and retrieving? This book provides organizations and individuals with a practical tool for creating and implementing vocabularies as reference tools, sources of documentation, and powerful enhancements for online searching.

Content

Controlled vocabularies in context -- What are controlled vocabularies? -- Relationships in controlled vocabularies -- Vocabularies for cultural objects -- Using multiple vocabularies -- Local authorities -- Constructing a vocabulary or authority -- Indexing with controlled vocabularies -- Retrieval using controlled vocabularies.

Abstract

Why doesn't your home page appear on the first page of search results, even when you query your own name? How do other Web pages always appear at the top? What creates these powerful rankings? And how? The first book ever about the science of Web page rankings, "Google's PageRank and Beyond" supplies the answers to these and other questions and more. The book serves two very different audiences: the curious science reader and the technical computational reader. The chapters build in mathematical sophistication, so that the first five are accessible to the general academic reader. While other chapters are much more mathematical in nature, each one contains something for both audiences. For example, the authors include entertaining asides such as how search engines make money and how the Great Firewall of China influences research. The book includes an extensive background chapter designed to help readers learn more about the mathematics of search engines, and it contains several MATLAB codes and links to sample Web data sets. The philosophy throughout is to encourage readers to experiment with the ideas and algorithms in the text. Any business seriously interested in improving its rankings in the major search engines can benefit from the clear examples, sample code, and list of resources provided. It includes: many illustrative examples and entertaining asides; MATLAB code; accessible and informal style; and complete and self-contained section for mathematics review.

Abstract

This short guide is intended to help librarians and OPAC system designers to make decisions about the design of displays of more than one subject heading. The authors stress that they offer guidance rather than standards or prescriptions; their clear prose is cautious and even the number of recommendations is limited. A 12-page introduction contrasts the "structural approach" and "strict alphabetical approach" to filing, showing examples and stating arguments for each. 7 chapters cover display of subdivisions, inverted headings, display of qualified headings, arrangement of numerical headings, display of subjects interfiled with names and titles, punctuation and messages to the user. Within each chapter, questions involving choices between two or more approaches are followed by brief statements of current practice (LC rules, ALA rules, and systems in existing OPACs) extensive examples demonstrating such choices, and arguments for and against each. The authors warn against ever assuming that the user knows the needed subject headings, and acknowledge that the best OPAC design often depends on the setting and on the user's understanding of the system. Although the topic may be beyond the purview of the authoring committee, the discussion here makes one yearn for interactive OPACs that can analyze the user's needs and provide appropriate guidance to whatever system is adopted
