Library of Congress Control Number (LCCN)
✨ With us, you won’t have to worry about delays, missed steps, or errors — we make sure your book meets the requirements and carries the proper Library of Congress credentials.
🏛 Library of Congress Control Number (LCCN)
The Library of Congress Control Number (LCCN) is a unique identification number assigned by the Library of Congress to titles most likely to be acquired into its collection. It is a vital identifier for publishers who want their books recognized and cataloged in libraries across the United States.
Why the LCCN Matters
Cataloging – Librarians use the LCCN to access the bibliographic record in the Library of Congress’s database.
Credibility – Having an LCCN signals that your book is officially documented and easier for libraries to locate.
Professional Presentation – The LCCN is usually printed on the copyright page (e.g., Library of Congress Control Number: 2001012345).
Eligibility Requirements
Only U.S. book publishers may apply.
The publisher must list a U.S. place of publication on the title or copyright page.
An editorial office in the U.S. must be maintained to answer bibliographic questions.
The book must be longer than 50 pages (many children’s books and shorter works do not qualify).
Books published exclusively in electronic form are ineligible.
How It Works
If you apply directly, you must:
Complete the Application to Participate to obtain an account number and password (1–2 weeks processing).
