Introduction to the Congress.gov Website  
Thursday, July 30, 2026, 2:00 pm - 3:00 pm ET

Congress.gov is a collaborative effort amongst the Library of Congress, the U.S. Senate, the U.S. House of Representatives and the Government Publishing Office to provide an official website for federal legislative information. It is a free resource that provides searchable access to bill statuses and summaries, bill texts, member profiles, the Congressional Record, committee reports, legislative process videos, and committee profile pages. Researchers can search across all the content in the system, refine their results, quickly see the status of a bill on a timeline, and view member pages with sponsored and co-sponsored legislation. Additionally, the system is designed to dynamically fit any size screen being used, mobile phone, notebook, and/or computer. Please join librarians from the Law Library of Congress, for an introduction to the Congress.gov website, its current and planned resources, and tips on how to best navigate this valuable online legislative service.  

Please note: This program is only being offered as a simultaneous online webinar. Please contact the Library to obtain webinar information for this program.

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 among the databases listed above, we provide a complete, searchable alphabetical list of titles. If you're looking for a particular journal but aren't sure where it's indexed or is available among the Library's online databases, try this list first.

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