Identifying and describing hundreds of the most valuable and up-to-date references for smaller libraries and media centers, this book can help librarians build better reference collections and answer everyday reference questions with confidence. Approximately 500 titles have been selected from "American Reference Books Annual" (Libraries Unlimited, 2002), as the most appropriate for smaller libraries. Written by practicing librarians and subject specialists, the detailed and authoritative reviews cover books and electronic resources published in 2001, with some from 2000. Reviewers describe each work, discussing its purpose, depth of coverage, and how it can be used. In many cases, materials are compared to similar titles, and reviews from professional journals are cited. In addition, each entry is coded for college, public, and school libraries. The book consists of four main parts: General Reference Works; Social Sciences; Humanities; and Science and Technology. Complete bibliographic and ordering information are furnished. Selected from the 2002 edition of American reference books annual. Includes Author/Title and Subject indexes. (AEF)
