The problem of what to try to teach students in the one-semester liberal a& chemistry course is a hardy perennial. Should we work on orbitals and bond hybridization or sir oollution and ~esticideresidues in food? ~ o t h e n b e r ~ e rs&tion, 's which I like, is to focus on some of the basic ideas and lanc a g e of chem~stry,in particular, the ideas and languagc ofclansrcal, nmeteenth-century chemistry. He argues tbat one can appreciate the meaning of chemical formulas and balanced equations with no more theoretical background than that available to a student 100years ago. It is the idea of chemical chance and its internretation in terms of atomsand molecules that isatreaoed, not the chemistry of particular elements and rompounds, nor of pn,ducts such as antacids and laundry bleach. Historical examples (for example, Pasteur's work on fermentation, the phlogiston theory, and Newland's theory of octaves) are used to illustrate points about how scientists work, but the book is not a history, nor a collection of historical anecdotes. The Daltonian atomic theory and the classical (Frankland/Kekule) valencies are used as the basis for writing formulas and balancing equations. The idea of molecular structure, including chirality, is developed starting from a brief consideration of crystal forms. A useful feature is that the simple rules for interpreting the organic chemist's bond-line ) eiven. formulas Ke.. . .

Energy relationships are introduced in connection with thermochemistry, and the concept of entropy is touched upon. Great emphasis is placed on the simplicity of the arithmetical calculations involved in stoiehiametry, although Rothenberger uses the term linear reasoning instead of proportionality. I found few errors and none of consequence, although there are places where I might prefer a different choice of words (ex., "linear reasoning" or "birthing plaie"). The text is short and meant to be covered ~~~~~~~~~

in less than a semester. Over a third of the pages are used for the Performance Objectives a t the end of each chapter and qoestions and problems, with answers given in an appendix. The remaining time to be used to talk about contemporary developments or applications. I have not taught a general studies course of this kind for a number of years, but experience with general ehemistry leads me to think that Rothenberger's approach is sound and one I would like to try. I t is perhaps worth noting tbat Rothenberger is a t Illinois State University, a leader in the number of chemistry majors it graduates annually. They do something rigbt with their undergraduate majors. I think this book shows that they do something rigbt with their nonmajors also. R. F.

Wolman's guide is a substantially expanded and updated edition of his 1983 book of the same title. The book is aimed a t practicing chemists and chemical specialists facing the expanding universe of chemical information. The book contains chapters and sections on all the main types of c b e m i d literature, including bath paper and computerized information. Introductory material on libraries and current awareness presents basic information on how to access information in libraries and how to keep up in a particular field of chemistry. As with several other chemical information source books (Robert M a i d ' s How to Find Chemical Information, Wiley, 1987, comes immediately to mind), the audience for this book is practicing chemists and particularly chemistry students. This book differs from others in the way the information sources are discussed. The prime intent of this book is to help chemists solve real information problems that they have in their daily work. The chapters on numerical data and synthetic reactions take chemists step by step through the various sources most useful in solving a particular information

problem. When more than one source exists, the various titles are discussed and evaluated as to currency, ease of use, and overlap, if any, with other sources. Sections an Beilstein and Gmelin, typically daunting sources for moat users, actually go through the steps required to find relevant data on a specific compound. Wolman then comparesthe data retrieved from these handbooks with that retrieved from other sources. This updated edition includes expanded coverage of computerized data bases, both bibliographic and numerical. Significant space and detail is devoted to conducting computerized lrterature searches in general and to Chemical Abstracts searching on the Dialoe. and STN networks in particular. In addit& to providing nitty k i t t y information an how to perform the searches, Wob man gives detailed analyses on how the systems differ and why results may vary between the two systems. The author's concluding chapters on expert systems in chemistry and on a look to the future in chemical literature provide one witha glimpse of what may be coming in the area of chemical literature and ways to access that literature. Far readers in the United States and Canada, the book shows a certain European slant. Discussion of classification schemes and vendors particularly highlight this point of view. If a fault may he found with the book, it is that a unified bibliography of sources mentioned is lacking. I t is somewhat disconcerting to have to read through text in order to find bibliographic information about a particular title. The extremely detailed table of contents and the index do help locate the references to desired titles. This hook would be useful pnrtreularly to chemistry and science librarians looking for guidance through the chemieal literature. Chemists teaching courses in chemical literature will find this a very welcome addition to their own libraries. Christine Johnston The University of TexabAustin Austin, TX 78712 ~~~~~~~~

combination of theEPAINIHMass Spectra Database, published by the National Bureau of Standards in 1978with supplements in 1980 and 1983,and the Wiley Registry of Mass Spectral Data, published in 1974. Both the Wiley collection ad NBS' EPAI NIH database have been and continue to be available in magnetic Lape, and the Wiley database is now also available un CD-ROM (compact disc-read only memory) for use with microcomputers. But for many spectrometrists and students, accessto print collections of spectra remains essential. This new collections brings together aver 40,000spectra from the EPAINIH datahase and over 70,000spectra from the Wiley collection to make over 150.000 s ~ e c t r afor 112.31N compounds. For this work, spectra have been evaluated, duplicatpi eliminated, and unsatisfactory spectra eliminated. A vast amount of checking has been done to select the best spectrum for a compound and to, if necessary, correct errors. The result is the largest, most comprehensive collection of electron ionization mass spectra in nrint format. In contrast with other data colledions de-. signed to find a substance that matches given ma88 spectral data, this collectiun is intended to be used to find mass spectral data for a particular substance. Spectra are organized in the seven volumes by increasing molecular weight, elemental composition and type of compound. Indexes by CAS Registry Number, compound name and composition provide additional access points. In the interest of saving space, the number of spectra presented on each page has been increased dramatically from the previous EPAINIH collection, and consequently the size of each entry has been reduced greatly. With each entry providing the bar graph spectrum and structure, as well as the molecular weieht. .. . formula. CAS Reeistrv number, sourced data, and name,the pages are crowded, and the data not easy to read. The shper number of spectra available in onerourcemake thiscollenion asubstantial improvement over either of the pre\,ious editions of the Wiley or NBS collections.
