Toxicology information systems: a historical perspective

Toxicology information systems have evolved swiftly from early, library-based bibliographic tools to advanced packages utilizing sophisticated computer and telecommunication technologies. These systems have evolved concurrently with the rapid expansion of the science of toxicology itself. Bibliographic files such as TOXLINE represent first attempts to handle the toxicology literature through on-line retrieval. Subsequent approaches applied the use of computers to provide literature-derived data, as in TDB or RTECS, or to capture data directly in the laboratory. Societal concerns about hazardous substances, manifested in legislation and regulations, have been responsible for the creation of many computerized systems. Advanced, integrated information management systems are being explored as a method of accessing a large number of independently maintained toxicology databases. Changes in information technologies such as the trend toward microcomputers and novel high-density storage devices will affect the future of toxicology information systems as will impending developments in toxicology itself related to biotechnology, analytical methodology, and alternatives to whole animal testing.
