Cataloging and indexing in library and information science refers to the goal of identifying the most important characteristics of an information source and describing those characteristics using a standard cataloging or indexing system. Libraries have developed sophisticated ways of categorizing information so that library users can most effectively find the materials they need. This book covers a wide range of important issues in the field, including archival finding aids, search engines, the major indexing and abstracting databases, subject guides, vendor-supplied cataloging records, metadata, and much more. Readers will gain an appreciation of the importance of the role of cataloging and indexing of library materials.
