Subject: ChemPrep - Reaction database Here is a new product on chemical reactions that appears to be worth examining. I found it on the website of ISI. To start with major research centres in chemistry such as IISc, NCL, IICT and some of the larger universities can take a trial subscription. Philadelphia, PA, USA - May 1, 1997 - The Institute for Scientific Information(R) (ISI) today announced the immediate availability of ChemPrep, a reaction database available on CD-ROM which provides researchers with graphical summaries of reactions, complete bibliographic and reaction information, and full author abstracts from the world's leading organic chemistry journals. ChemPrep is searchable by substructure, transformation, or text. Data will be available for over 300,000 reactions from 1986 to the present. More than 35,000 new organic syntheses are indexed in ChemPrep each year, providing comprehensive information on the reactants and products of each reaction, including amounts and concentrations of chemicals used and reaction conditions. The new database is updated quarterly. "Chemists choose synthetic methods every day, but have not always had convenient and affordable access to a timely and comprehensive reaction database" said Matthew Clark, Ph.D, Director of Marketing and New Product Development, ISI. "ChemPrep offers CD-ROM access to more than a decade of published synthetic methods. With ChemPrep, chemists will have ready access to the information they need." An annual subscription to ChemPrep includes three quarterly, cumulative updates and an annual archival disc, as well as all the necessary software for drawing and searching structures and text. Operating requirements specify an IBM or 100% compatible PC (minimum 486 with 33Mhz required); MS-DOS version 5.0 or higher; Windows version 3.1 or later; 8MB RAM; 4MB free disk space; and a CD-ROM drive. The Institute for Scientific Information, headquartered in Philadelphia, Pennsylvania, has been creating innovative information tools for the scientific community for more than forty years. Its extensive line of advanced research products, available in diverse media, provides fast, effective ways to search the world's journal literature. ISI produces weekly current awareness tools such as Current Contents(R), as well as a line of Citation Databases including the Science Citation Index(R). Other chemistry products from ISI include Index Chemicus(R), Current Chemical Reactions(R), and Reaction Citation Index(TM). Ordering of full-text articles covered in the ISI database is available through the ISI document delivery service, The Genuine Article(R).
