Library of Congress – LCCN

LCCN Assignment
If you’d like to make your book available to libraries, we can help you obtain a Library of Congress Control Number, or LCCN, so your book is given a unique identifier and is eligible for library cataloging nationwide.

An LCCN for Your Book
Libraries use the Library of Congress database, as well as other databases, to stay up-to-date on available titles. Make it easier for them to purchase your book by registering for a Library of Congress Control Number (LCCN)–a unique identification number that the Library of Congress assigns and uses for cataloging and other book-processing activities.

How It Works
Your personal representative will complete an application for your LCCN on your behalf and submit one copy of your book to the Library of Congress to be considered for cataloging. Here’s how the process works:
1. Purchase the LCCN Assignment service before you approve your final proof. Note: After you have approved your proof the book is no longer eligible to begin this service.
2. We will complete an application for your LCCN on your behalf and submit it to the Library of Congress.
3. We will send you your LCCN within ten business days.
4. We will submit one copy of your book to the Library of Congress to be considered for cataloging. Note: Submission for cataloging does not guarantee acceptance into the Library of Congress. To find out if you book has been cataloged, we suggest occasionally checking the Library of Congress Online Catalog.
