Dialog, a Thomson business and provider of online-based information services and integrated information solutions, has reorganized and expanded its Beilstein organic chemistry collection. With research dating back to 1771, the Beilstein collection is a resource for research and analysis in the field of organic chemistry. Researchers and professionals working in such industries as chemistry, pharmacology, biotechnology, and energy, as well as law firms and government regulatory agencies, use Dialog to search and retrieve Beilstein content.
Dialog will offer the Beilstein collection in three separate files, Beilstein Facts, Beilstein Reactions, and Beilstein Abstracts that may be searched simultaneously or individually. Beilstein Facts (File 390), with research back to 1771, provides chemical structures and details on the properties of organic chemicals, including melting points, density, spectral data, and more. Additional types of information, including pharmacological, ecological, and toxicological data, now have been added. There is no charge for searching in File 390 and Dialog recently lowered record output fees for records from File 390. Beilstein Reactions (File 391) contains data for more than 9 million chemical reactions and preparations. Data retrieved through File 391 now is linked to the properties in File 390 and the abstracts in File 393, allowing for follow-up research. Searching is free in File 391, with nominal charges for records outputted. Beilstein Abstracts (File 393) includes citations from literature and patents published from 1771 through 1979, along with citations with abstracts of articles published since 1980 and drawn from approximately 175 journals. References may be supplemented with data retrieved from Dialog's portfolio of scientific literature and patents. File 393 has now been enhanced with Alerts, enabling users to be notified via email when relevant new data is added.
