This latest addition to Macmillan's series of comprehensive core science encyclopedias (previous sets dealt with physics and earth sciences) will be of particular interest to readers of this Journal, for it is edited by longtime Journal of Chemical Education editor Joe Lagowski, assisted by a board of five distinguished associate editors. The attractively priced set offers clear explanations of the phenomena and concepts of chemistry and its materials, whether found in industry, the laboratory, or the natural world. It is intended for a broad spectrum of readers-professionals whose work draws on chemical concepts and knowledge (e.g., material scientists, engineers, health workers, biotechnologists, mathematicians, and computer programmers), science teachers at all levels from kindergarten to high school, high school and college students interested in medicine or the sciences, college and university professors, and laypersons desiring information on practical aspects of chemistry (e.g., household cleaning products, food and food additives, manufactured materials, herbicides, the human body, sweeteners, and animal communication).

Although some of its 402 writers are authorities from 16 countries outside the U.S., most are U.S. academics and many are frequent contributors to this Journal. Its excellent, lucid writing, useful organization, and comprehensive range make it an indispensable source of information about the "central science".

The Encyclopedia's 684 articles discuss a broad range of topics generally associated with chemistry, its subdisciplines, and branches. The user will find entries on elements and compounds, including name origins and properties; descriptions of processes and mechanisms; explanations of the basic nature of matter; and a wide range of entries dealing with applications of chemical substances, including drug, tobacco, and caffeine addiction, chemical warfare, oil recovery, medical devices, and use of asbestos in building. Many articles are particularly current or environmentally relevant (e.g., ethics in science, green science, fullerenes, ozone depletion, the PCR, space chemistry) or oriented toward students (e.g., career options and career planning, literature searches). There are biographies of 100 past and contemporary chemists and physicists (four of them women-Curie, Hodgkin, Joliot-Curie, and Meitner) from Roger Adams to Robert Burns Woodward. Pages are double-columned. Entries range in length from one paragraph to a dozen pages, are alphabetically arranged, and include cross-references (in small capital letters) to guide readers to related entries and specific topics. Entries for common substances invite the reader to experience the breadth and depth of the chemistry associated with them. Most entries contain carefully selected bibliographies, with references (some as recent as 1996) primarily to readily available books and journals such as the Journal of Chemical Education. More than 1500 illustrations of equations, chemical structures, reaction schemes, and principles clarify the concepts being discussed.

Lists of common abbreviations and symbols (8 pp) and journal abbreviations (3 pp) and a 1994 periodic table (which, of course, does not include the latest IUPAC-recommended names for elements 104 to 106) appear at the beginning of each of the four volumes. The first volume also includes a 9-page synoptic outline of articles, arranged according to concepts and particularly useful for teaching purposes; a 20-page alphabetical list of articles-from ab initio calculations to zinc-and their authors (a few articles have as many as four coauthors); and a 20-page alphabetical list of contributors, their professional affiliations, and article names. The last volume includes an up-to-date list of Nobel chemistry laureates through 1996 and a detailed, comprehensive index (150 pp).

In many cases the best authorities have been selected as authors (e.g., Alton J. Banks for elements, Gillespie for VSEPR, Laidler for kinetics, Olah and Suryah Prakash for super acids, and Seaborg for actinides); but in other cases the authors do not seem to have any special expertise for their topics. Also, some of the biographies (e.g., Davy, Lavoisier, Pasteur, and Pauling) do not include recent books published as early as 1995 in their bibliographies. Geoff Wilkinson's death, which occurred a full year before the encyclopedia's publication, is not included in his biography. Errors are few and limited mostly to names, such as Adolph for Adolf (von Baeyer), Jons Jakob for Jons Jacob (Berzelius), Bronsted-Lowery, Henry for Henri (Le Châtelier), Ferdinand-Henry-Federic for Ferdinand-Henri-Frederic (Moissan), and Schonbein for Schönbein. The nonword liquification is used for liquefaction. These minor shortcomings notwithstanding, I am pleased to recommend the set as a handy, first-line, user-friendly reference source.

One of the features of this comprehensive compendium of useful knowledge about general chemistry that make it attractive to chemical educators is its relatively modest price ($400) compared to the prices of other multivolume chemical encyclopedias such as Kirk-Othmer, Ullmann, Comprehensive Coordination Chemistry, and Comprehensive Organometallic Chemistry, whose costs are in the thousands of dollars, pricing them out of the range affordable to individuals. Also, unlike these specialized encyclopedias, the Macmillan set covers all of chemistry. The only possible competitor within the price range of an individual buyers, the one-volume McGraw-Hill Encyclopedia of Chemistry, 2nd edition, Sybil P. Parker, Ed. (McGraw-Hill: New York, 1993, $99.50) went out of print in November 1996.
