A revised and updated guide to reference material. It contains selective and evaluative entries to guide the enquirer to the best source of reference in each subject area, be it journal article, CD-ROM, on-line database, bibliography, encyclopaedia, monograph or directory. It features full critical annotations and reviewers' comments and comprehensive author-title and subject indexes. The contents include: mathematics; astronomy and surveying; physics; chemistry; earth sciences; palaeontology; anthropology; biology; natural history; botany; zoology; patents and interventions; medicine; engineering; transport vehicles; agriculture and livestock; household management; communication; chemical industry; manufactures; industries, trades and crafts; and the building industry.

**** The Brit counterpart to Sheehy (in which it is recommended). The new edition places the author, title, subject indices in each volume. Many entries cite reviews from other sources. Rather tiresome recitation of selected chapter contents. 6,000 entries with references in the annotations to one or two thousand further books. Covers sci- tech and paleontology, anthro, patents, medicine, trades and crafts. Arranged by UDC classification. Provides no prices. Available in the US from American Library Assn.
