Can I get a Library of Congress (LOC) catalog card number assigned to my book and what will it cost?
e can apply for your LOC. Some examples of books not eligible for a LOC are: books under 50 pages (except children’s literature and genealogy); religious instructional materials for classes at all grade levels; vacation Bible schools, confirmation studies, etc.; and expendable educational materials such as laboratory manuals, teachers’ manuals, programmed instruction test sheets, workbooks, activity books, etc. We will file for your LOC for no charge when you have an ISBN. See copyright filing for information on this.
