Library of Congress Number
The Library of Congress number is used by the United States' central library to track submissions for the library's permanent collection. We'll submit a copy of your book to the Library of Congress, and arrange for a card catalog number to be assigned to your book.
The Library of Congress reserves the right to refuse cataloguing titles. They do not provide catalog numbers for books under 50 pages unless they are a children's book. They also do not catalog transitory or consumable materials, such as coloring books, comic books, and cut-out books. The Library of Congress will not assign card catalog numbers for books that fall under any of these categories.
Note: This service can be purchased together with the publishing package or during the submission of the manuscript. This cannot be purchased for book titles that are already published.
