How Do You Get a Library of Congress Number?

A Library of Congress Control Number (LCCN) is a unique identifier assigned by the Library of Congress to bibliographic records for books, serials, and other published works. Having an LCCN helps libraries, booksellers, and researchers locate your title quickly in catalogs worldwide. Because of that, if you are an author, publisher, or self‑publisher looking to make your work discoverable, obtaining an LCCN is a straightforward process that adds credibility and improves distribution chances. Below is a complete guide that explains what an LCCN is, who needs one, and the step‑by‑step procedure to acquire it.

What Is a Library of Congress Number?

The Library of Congress Control Number (LCCN) is a serial number prefixed with “lc” (e., lc 2023012345) that the Library of Congress assigns to a bibliographic record in its online catalog. Even so, g. It is not an ISBN, although the two numbers often appear together on a book’s copyright page.

• Uniquely identifies a specific edition of a work in library systems.
• Facilitates interlibrary loan and catalog sharing across the United States and internationally.
• Supports metadata exchange with vendors, bibliographic utilities, and digital repositories.
• Enhances discoverability in library catalogs such as WorldCat and the Library of Congress’ own online public access catalog (OPAC).

Because the LCCN is tied to the bibliographic record rather than the physical item, a single title can have multiple LCCNs if different editions (e.And g. , hardcover vs. paperback) are cataloged separately.

How the LCCN System Works

Before diving into the application steps, it helps to understand the mechanics behind the number:

1. Bibliographic Record Creation – The Library of Congress creates a MARC (Machine‑Readable Cataloging) record for the item based on information supplied by the applicant.
2. Number Assignment – A sequential LCCN is generated and attached to that record.
3. Distribution – The record is made available via the Library of Congress Catalog, OCLC’s WorldCat, and other bibliographic services.
4. Linking to ISBN – While separate, the LCCN is often displayed alongside the ISBN on the copyright page, allowing cross‑referencing.

The LCCN does not convey copyright protection; it is purely an identification tool.
