$299
A Library of Congress Control Number (LCCN) makes it faster and easier for libraries to catalog your book, increasing its chances of being accepted into their collections.
While not strictly required, many libraries prefer — and some even expect — books to have an LCCN before considering them for placement.
For self-published authors, securing an LCCN is a simple step that signals professionalism, credibility and “library-readiness” — helping your book stand out from the competition.
Scroll down to learn how this option works and why it’s an essential investment in your book’s success.
Make Your Book Library-Ready with a Library of Congress Control Number (LCCN)
If you plan to distribute to libraries, or want your book to be professionally recognized and discoverable, an LCCN is a must. Select the Library of Congress Control Number now as part of your publication setup so your book is fully library-ready.
Why It Matters
- A Library of Congress Control Number (LCCN) allows libraries to easily catalog your book using official systems.
- Without an LCCN, many library acquisition departments may decline to carry your book — these systems often rely on LCCNs for classification and indexing.
- An LCCN acts as a badge of legitimacy, helping your book stand out in library catalogs, academic settings and when pitching to bookstores or reviewers.
What’s Included
- Pre-Publication Registration. We submit for the LCCN before your book is published so the number can appear on the copyright page.
- Official Registration & Cataloging. Outskirts Press handles the paperwork with the Library of Congress and ensures correct assignment.
- Copy to Library of Congress. Once your book is published, we send copies to the Library of Congress and the CIP (Cataloging in Publication) division.
Value You Get
- Credibility and trust with libraries, book sellers and institutions.
- Higher chances of being listed properly in library catalogs, which increases discoverability.
- Better marketing messaging — you can promote your book as “Library Ready” or “Officially cataloged.”
Important Notes
- An LCCN cannot be added after publication — it must be added during the publishing process.
- Inclusion in library collections is not guaranteed merely by having an LCCN, but having one is often a minimum requirement for many libraries.
