Library of Congress
Verified working Aug 3, 2026
A massive public gateway to U.S. cultural and legislative collections.
The Library of Congress site provides online access to a wide range of digitized materials, including books, photographs, maps, recordings, newspapers, manuscripts, web archives, and 3D objects. It also connects visitors to the Library’s catalog, research help, exhibitions, events, Congress.gov, and the U.S. Copyright Office.
Why it stands out
- Combines library catalog records, digitized primary sources, exhibitions, and expert research services in one official institution site.
- Covers unusually diverse formats, from manuscripts and maps to audio, video, web archives, software, and 3D objects.
- Includes authoritative U.S. legislative and copyright pathways through Congress.gov and Copyright.gov.
- Provides curated public-domain and rights-friendly sets for reuse, not just item-by-item search.
Good to know
- Not every Library holding is digitized, so some materials require catalog requests or in-person research.
- Rights and reuse status vary by item; users should check the record details before publishing or remixing materials.
- The collection is especially strong for U.S. history and federal materials, but it is not a universal archive of all countries or topics.
Under the radar: When you need images or documents you can confidently reuse, start with the “Free to Use and Reuse” collections instead of beginning from the global search box.

Historians, teachers, students, and genealogists can find primary sources from a major U.S. national collection. Search historic photographs, newspapers, maps, recordings, and manuscripts for research projects. Use Ask a Librarian or research center pages when a collection requires expert guidance. Plan an in-person visit to exhibitions, reading rooms, or public programs. Track U.S. federal legislation through the linked Congress.gov service.
Search across many collection formats; online catalog and digital collections; themed exhibitions and event listings; teacher and education resources; research centers and Ask a Librarian support; links to Copyright.gov and Congress.gov; curated “Free to Use and Reuse” sets.
Technical Notes
- LOC provides documented APIs and JSON access for many loc.gov search and item records.
- Many digitized image resources are available through IIIF-compatible services for structured image retrieval.
