Library of Congress

What Library of Congress does

The Library of Congress is the national library of the United States and the research library for the U.S. Congress, established by Congress in 1800 under 2 U.S.C. § 131 and headquartered at 101 Independence Ave SE, Washington, D.C. It is a federal government institution, not a private entity, employing approximately 3,200 personnel and operating on an annual budget of $719.4 million in federal appropriations and other revenues. The Library holds the largest collection in the world, with more than 160 million items including books, manuscripts, films, sound recordings, maps, and government documents, supplemented by the National Audio-Visual Conservation Center in Culpeper, Virginia, which houses approximately 145,000 nitrate film reels.

The Library's core products and programs include the National Recording Registry (700 titles of culturally significant sound recordings), the National Book Festival, the Veterans History Project, the By the People crowdsourcing transcription platform (powered by the open-source Concordia platform), the Law Library of Congress legal research reports, and the Congressional Serial Set digitization initiative with the Government Publishing Office. Its technology stack includes digital preservation infrastructure, machine learning experiments for metadata automation (Exploring Computational Description), content provenance standards development (C2PA for G+LAM working group formed January 2025), and integrations with library technology providers including Springshare, ExLibris, OCLC, Granicus GovDelivery, and GitHub-hosted open-source repositories.

The Library's business model is non-commercial: it is funded entirely through federal Congressional appropriations and supplemented by philanthropic grants (e.g., $15M from the Andrew W. Mellon Foundation in 2021). All services — physical visits, digital collections access, research assistance, educational programs, copyright registration, and the National Book Festival — are provided free of charge to Congress and the American public. Customer segments include U.S. Congress (legislative research support), K-12 educators and students (Teaching with Primary Sources), U.S. veterans (oral history preservation), and the general public/scholarly researchers. Distribution occurs through LOC.gov, Congress.gov, Copyright.gov, physical locations, and a multi-channel marketing presence across social media, themed blogs, and email newsletters.
