Research articles of interest to biochemists may appear in many types of research journals. Research libraries do not have the funds necessary to subscribe to every journal, nor do scientists have the time to survey every current journal copy for articles of interest. Two publications that help scientists to keep up with published articles are Chemical Titles (published every 2 weeks by the American Chemical Society) and the weekly Current Contents available in hard copy and computer disks (published by the Institute of Science Information). The Life Science edition of Current Contents is the most useful for biochemists. The computer revolution has reached into the chemical and biochemical literature, and most college and university libraries now subscribe to computer bibliographic search services. One such service is STN International, the scientific and technical information network. This on-line system allows direct access to some of the world s largest scientific databases. The STN databases of most value to life scientists include BIOSIS Pre-views/RN (produced by Bio Sciences Information Service covers original research reports, reviews, and U.S. patents in biology and biomedicine), CA (produced by Chemical Abstracts service covers research reports in all areas of chemistry), MEDLINE, and MEDLARS (produced by the U.S. National Library of Medicine and Index Medicus, respectively cover all areas of biomedicine). These networks provide on-line service and their databases can be accessed from personal computers in the office, laboratory, or library. Some... 

MEDLARS. The U.S. National Library of Medicine s (NLM) Medical Literature Analysis and Retrieval System contains over 30 bibliographic databases covering medicine, dentistry, nursing, pharmacology, toxicology, cancer, veterinary medicine, and allied health professions (37). The MEDLARS electronic storage and retrieval system was established at NLM to provide bibliographic access to NLM s biomedical literature collection. 

The Toxicology Information Services at the Karolinska Institutet 1n Stockholm, Sweden, publish a monthly bulletin entitled Teratology Lookout. This excellent source of references of interest to experimental teratologists and clinicians is compiled by an advisory panel. The secondary sources Biological Abstracts, Biological Abstracts/RRM, and Chemical Abstracts and the MEDLARS data bases are scanned by the use of computer profiles to spot pertinent material. Keywords have been added to each reference, and most references include author addresses. The contents are divided into seven...

MEDLINE (MEDlars on-LINE), NLM s on-line data base on the medical literature of the world, indexes its entries by use of MESH (MEdical Subject Heading) terms, which is a controlled vocabulary. When searching on-line, terms entered default to the MESH heading index unless a modifier specifies that another index is searched. The following MESH headings are useful for finding teratology information on MEDLINE ... 

The ETIC file has been divided into three different portions by the MEDLARS system. The ETIC citations from 1981 to the current date are found on TOXLINE. References dated 1976 to 1980 appear in a separate file entitled T0XBACK76, while those citations through 1975 and previous years are found in T0XBACK65. Search strategy on these three files is identical. Terms may be entered singly or may be combined by means of the Boolean operators AND, OR, and AND NOT.

In 1981 a new list with 86 additional substances became available (ref. 8). The computer search of the RTECS was reasonably straightforward at that time. The key word "teratogen" was used and the RTECS data base searched for the names of compounds under this classification. The size of the printed file was reasonable (500-600 entries). A copy of the file could be posted in the laboratory, with a short explanation that the list of teratogens should be viewed with caution due to the fact that data from the RTECS are unevaluated and that uncertainties exist about animal-human extrapolations. Any librarian having access to NLM-MEDLARS (National Library of Medicine-...
