The Online Library System (OLS) for EPA’s National Library Network consists of several related databases that comprise the shared library catalog. Use OLS to locate books, reports, journals, and audiovisual materials on a variety of topics. Then search Addison or use interlibrary loan to access the material.
The material on OLS is updated every two weeks, and may be searched in many ways, such as by title, author, and keyword. In addition to the primary catalog, there are databases in OLS associated with special collections:
You can search OLS to find information on a specific publication, or you can search for all of the books and reports that EPA has on a particular topic or by a particular author. Once you retrieve records for publications that interest you, there are several ways that you can obtain those publications.
For site security purposes and to ensure that this service remains available to all users, EPA employs monitors and filters to identify and block unauthorized attempts to upload or change information, or otherwise cause damage to the information on our Web pages. Unauthorized attempts to upload or change information on this site are strictly prohibited and may be punishable under the Computer Fraud and Abuse Act of 1986 and the National Information Infrastructure Protection Act.
