This revision of Ralph Perkin's "Book Selection Media" (1967 edition) expands by almost half that edition, with much of the material from the earlier edition being retained and updated. (See ED 017 506 for earlier edition entitled "Book Selection Media, A Descriptive Guide to 170 Aids for Selecting Library Materials.") In addition to general guides for all ages, also included are guides for specific age and interest groups. A number of the works included provide background for parents and teachers when selecting books. Lists of pamphlets usually are grouped according to the topics they cover. The annotations appear in the following format: Title, Author-Publisher, Publication Data, Purpose, Scope, Subject Headings, Similar Tools, Special Features, Usefulness, and Cost. There are seven indexes to this book, as follows: Aids to Making Selections for Children; Aids to Making Selections for Teenagers; Selection Aids for College Students and Adults; Selection Aids for Teacher-Parent Background; Selection Aids for Librarians; Title Index; and Author-Publisher Index.
