Law and Public Policy

The Interior Library Reference Staff maintains access to the Lexis Advance, Westlaw and PACER online databases. Departmental employees can visit the Interior Library or contact the Library by phone at (202) 208-5815 or via the Library's Questions and Comments form if they would like a reference librarian to conduct a work-related search in any of these databases.

Find Electronic Books and Journals By Title

To help you determine whether and where a needed electronic book or journal is available online, we provide a complete, searchable alphabetical list of titles. If you're not sure where to find a something online, try this list first.

The list combines the full-text journals and other materials in all the database services to which the Library has access.

Also included are some single subscriptions as well as selected open access books and journals. Most entries include coverage dates, and all entries have links directly to the requested title.

Please direct your questions on database searching strategies to a Reference Librarian.
