example is the chromatographic separation coefficient when mtention inversion occurs. One should stress that each response should be mcdelled separately and that developing composite response functions should be carried out in a second stage, if at all, because there are better alternatives.

Expert Systems for EnviApplications, ronmental edited by Judith M. Hushon (Symposium Series 431) American. Chemical Society, Washington, DC. 1990, viii + 232 pages, VS$49.95, ISBN O-8412-1814-5 This book is based on a symposium sponsored by the Division of

=

Chemical Information at the fall 1989 ASC meeting. The first chapter presents a summary of environmental expert system ~velopment including an informative table of existing applic~ions. The next two chapters focus on the management of expett system development as well as procedures for knowledge acquisition and system validation. The fourth chapter provides a good introduction to neural networks, the relation between neural nets and expert systems, and brief descriptions of some applications. The remaining 70% of the book (12 chapters) are case studies of expert system applications. These applications range from systems which supply high-level expertise to those which provide predictive modelling. A number of approaches to system development are illustrated including the use of probung languages (PROLOG), tool kits (KES), and shells (KnowledgePro). Chapter 8, “A citizen’s

helper for chemical information” describes the use of Apple’s HyperCard program as an expert system to provide info~tion about hazardous materials such as health effects and safe storage facilities. The book’s focus on environmental applications limits its audience to persons working in this area. There are more appropriate references for f~li~zing chemists with expert systems. While the specific software used for system development may have changed since 1989, the methods of organizing information for knowledge bases have not. The case studies provide excellent examples of these methods. The book is recommended to persons concerned with providing environmental information. FRANK A. SETI’LE, JR.

normal E-Mail messages to LISTSERV. The text of these messages are interpreted as ins~ctions. It is possible to get quite sophisticated in the LISTSERV language, but a few simple commands are all you really need to learn. Tom O’Haver has set up an online discussion group for the International ~e~~t~cs Society, using the LISTSERV facility. This

group is labelled “ICS-L”. To sign on to this group, just send a message to LISTSERV Thereafter, to send mail to all members of the discussion group, send a single message to ICS-Land it will take care of distributing it about. To join the ICS-L discussion group, send the following E-Mail message to “[email protected]*‘:

ISI to Release Five-Year Cumulation of Current Chemical Reactions Data base on magnetic Tape The Institute for Scientific Information (ISI) has announced that this summer, it will release a cumulation of its Current Chemical Reactions Data base, covering the years from 1986 through 1990. In addition to giving users instant electronic access to five years’ worth of chemical reactions in a single file, the new CCR cumulation will: -Support conversion and combination searches across five data base

yeam -Feature more variations and multiple references, showing new relationships and new connations between different synthetic methods; -Require less storage space than the five annual files; -Contain updated info~ation. The Current Chemical Reactions Data base was the first large, inhouse data base of new synthetic methods designed for REACCS

software. It covers the new synthetic methods for organic and medicinal compounds, agrochemicals and polymers from the world’s leading organic chemistry journals and US registered patents. The CCR Data base contains both single- and multi-step syn~~c methods. Each step of the multi-step sequences is a separate, searchable reaction, All synthetic methods represented in the data base include a key step reaction indicator, as well as an overall reaction indicator.

Bruce Kowalski appointed to first endowed chemistry professorship at ~n~e~~y of Washington The University of Washington Board of Regents appointed Professor Bruce R. Kowalski to the first endowed professorship in the Department of Chemistry, established with support from ten corporate donors. This is the first endowed professorship at the University of Washington arising from a consortium arrangement, according to Vie Provost for Research, Alvin L. Kwiram. The professorship, which was matched by state funds, is in the field of analytical chemistry. The corporate donors are sponsors of the National Science FounIndustry/University dation Cooperative Research Center for Analytical Chemistry Process (CPAC) at the University of Washington. The Center is an interdisciplinary research venture aimed at developing new analytical and sensor technology for industrial process
