This chapter presents a bibliography of information sources about toxicology. Growth in scientific literature is attributed to several factors. First and foremost is the growing need for all practitioners—research scientists, policy analysts, communication specialists, librarians, and journalists—to stay abreast of current information trends and resources in the rapidly evolving field of toxicology. Second is the wider dissemination of this information via newer electronic systems, such as the Internet and the World Wide Web. Several print and online bibliographic databases are also quite useful for retrieving relevant resources on information and data management for toxicology and environmental health. This bibliography covers a broad span of issues related to the management of toxicology data and information. The bibliography is grouped into four main areas: Internet and World Wide Web sites and services; other electronic services, products, and systems; general data and information handling and management; and Material Safety Data Sheets.
