A Library of Congress Number (LCCN) helps a library properly catalogue a book and helps facilitate distribution through the United States library system, although it does not guarantee carriage by any or all libraries, as those decisions are up to each individual library branch's acquisitions department.

With this optional upgrade, Outskirts Press acquires one unique Library of Congress Control Number for your book, provided the book is not deemed "disposable" by the Library of Congress. "Disposable" books, by their definition, include any books that are meant to be "used" once and then discarded, such as workbooks, quiz books, puzzle books, game books, coloring books, etc. The LCCN is placed on copyright page of all your hardcopy formats (paperback and/or hardback) in standardized format. We also submit the appropriate editions of your book to the Library of Congress after publication.

An LCCN helps the US Library System properly order and categorize your book.  Submitting copies to the Library of Congress is also a typical (although not required) step in the publication of books. One physical copy of your printed, published book is mailed to the Library of Congress in Capital Heights, Maryland. Another is mailed to the Cataloging in Publication Division of the Library of Congress in Washington D.C. Although two printed copies of the book will be shipped to the Library of Congress, the Library of Congress is under no obligation to enter said book into their online catalogue or list it on their website. Their choice to do so is entirely at their discretion and outside of the control of Outskirts Press.

Since the LCCN is printed on the copyright page during publication and printing, it cannot be acquired after publication. So if you are interested in this option, the only time to get it is during pre-production prior to book formatting.

The Library of Congress Number Option fee becomes non-refundable once purchased.

Authors who order our Private Label Imprint and ISBN option should acquire their own LCCN directly from the Library of Congress by registering with the Library of Congress under their own publishing imprint. If the Library of Congress Number Option is purchased, the LCCN Number we supply will be the one supplied to us as the publisher on record with the Library of Congress, regardless of whether you publish under the Private Label Imprint.
