Book Reviews COSMETICS-PERFUMERY THESAURUS, by Hilda Feinberg. CCM Informa- tion Corp., New York, 1972. 106 pages. Price $12.95. This book is the first of a projected series of "thesauri" planned by the publishers, and is stated to be "first and foremost a practical tool for the vorking indexer or designer of an indexing system for the discipline or subject which it covers." The greatest value of this •vork •vill probably lie in its use as a stan- dardized system for choosing one of several possible terms, notations, or methods for indexing items of infor- mation. Such uniform notation •vill undoubtedly facilitate literature search, and •vill constitute a neces- sary adjunct to the computerized in- formation retrieval •vhich looms in the not too distant future. This is not an encyclopedia nor a dictionary, although descriptive notes are rather unevenly used, es- pecially under "Odors-Fragrance Types." Ho•vever, one should not ex- pect to use this book to find defini- tions. The author disclaims completeness and perfection, and invites criticism from users in order to improve suc- ceeding editions. Cellulose is listed, but not cellulose nitrate, nor cellu- lose derivatives in general. No posi- tion appears to have been taken on the ambiguous term "perfume com- pounds." This is, therefore, a book vhich vill serve mainly as a guide to in- dexers and literature searchers. It represents a capable and veil- planned effort to systematize the de- scription of information pertaining to cosmetic and perfume science and technology.--PAun LAUFFEa--Apache Junction, Arizona FORMULACION DE Los AEROSOLS (FoaMULaTIO• OE AZROSO•,S), by Dario Rodriquez Devesa. Dario Rodriquez Devesa, Avda. General- isimo, 118 Madrid 16, Spain, 1972. xvi + 933 pages, indexed. Price 4, 200 ptas. ( about U.S. $68.00). This book covering various aerosol formulations is vritten entirely in Spanish and should be of particular interest to aerosol personnel in the Spanish-speaking countries as well as Spanish-speaking personnel in the aerosol industry in the U.S. The book has been four years in preparation by the author and publisher and covers all types of aerosol products. It is divided into 23 chapters and 829
