The OLS is a computerized list of bibliographic citations compiled by the library network of the Environmental Protection Agency (EPA). It consists of several related databases and can be used by anyone to search for books, documents, journals, and other materials. In addition to the national catalog, materials on hazardous wastes, clean lakes, EPA Region 1, and the chemical collection system are included.

Chapters cover the following topics: (1) starting the system; (2) selecting a database; (3) setting parameters; (4) the patron menu; (5) search options; (6) other options; and (7) printing from the OLS. An appendix lists stopwords used in indexing databases. A list of EPA libraries is included. (SLD)
