Let’s Talk About the Library of Congress, Part Two


How can an Independent Author get their book into the LOC?

Getting your self-published book into the Library of Congress collection

While the Library of Congress (LOC) accepts self-published titles in various areas, such as genealogies, local histories, veterans’ histories, and certain other works that demonstrate unique expertise or perspectives, it’s important to understand the process and requirements involved. 

Here’s how an independent author can increase the chances of getting their book into the Library of Congress:

1. Apply for a preassigned control number (PCN)

  • The Library of Congress offers a program called PrePub Book Link, where US-based authors and self-publishers can apply for a PCN (Preassigned Control Number) for their forthcoming print books.
  • The PCN allows the LOC to create a brief bibliographic record for the book before publication and makes it easier for other libraries to catalog it.
  • To be eligible for a PCN, you must be a US-based author or publisher, with a US place of publication listed in your book, a US editorial office, and a US phone number.
  • You’ll need a Bowker-purchased ISBN for each print format of your book, as ISBNs from Amazon, IngramSpark, Barnes & Noble Press, or Draft2Digital are not accepted for this program.
  • Apply before the book’s publication date using the PrePub Book Link platform.
  • The application requires information about your book, including general details, contributor information, title page details, series information (if applicable), ISBNs, and a book summary or synopsis.
  • PCN processing typically takes 1-2 weeks, so apply well in advance of your publication date. 

2. Submit a print copy of your published book

  • After your book is published, you are required to send a printed copy to the Library of Congress to fulfill the mandatory deposit requirement for PCN participants.
  • Failure to submit the published copy can result in ineligibility for inclusion in the LOC’s collections and potential suspension from the program.
  • The LOC prefers the best available print copy, so if you have both a paperback and a hardcover, send the hardcover version. 

3. Be aware of the selection process

  • Submitting your book with a PCN does not guarantee that it will be added to the Library of Congress’s permanent collection.
  • The LOC staff reviews the submitted books and selects those that align with their collection development policies, which include prioritizing works on American history, genealogy, and culture.
  • If your book is selected, the PCN transforms into an LCCN, and the brief bibliographic record will be updated and made public in the Library of Congress catalog.
  • If your book is not selected for the permanent collection, it may be directed to the LOC’s surplus book program. 

Additional tips for increasing your chances

  • Ensure that your book is of high quality and professionally produced with appropriate formatting and editing.
  • Consider seeking professional reviews from recognized library review publications like Library JournalKirkus Reviews, or Publishers Weekly.
  • Provide detailed and accurate metadata, including BISAC codes, descriptions, age ranges, and regional information.
  • Consider using IngramSpark for print book distribution, as libraries are more likely to order books available through trusted distributors like Ingram and Baker & Taylor.
  • Engage with libraries and foster local demand for your book by participating in author events, workshops, or getting involved with local “Friends of the Library” groups. 

By following these steps, independent authors can enhance their chances of having their work included in the Library of Congress collection and made available to a wider audience through the national library system.
