ABSTRACT

NLM’s Specialized Information Services Division (SIS) is responsible for extensive information resources and services in toxicology, environmental health, chemistry, and other topics. For example, NLM SIS’s TOXNET (TOXicology Data NETwork) is a large set of widely used databases. TOXNET’s TOXLINE database provides bibliographic information covering the toxicological, biochemical, pharmacological, and physiological effects of chemicals and incorporates citations from NLM’s PubMed/MEDLINE and other sources.
