Abstract
The Code of Federal Regulations, Title 21 (21 CFR), contains the US. federal regulations for every product regulated by the Food and Drug Administration and Drug Enforcement Administration, including pharmaceuticals, veterinary products, medical devices, cosmetics, and foods. A new online database, 21CFR Online, now allows access to the full-text of these regulations as file CF2l on BRS and Data-Star. In this article, the structure of the file is outlined; sample searches illustrate some of the features and content of the database.
