What are we doing? We just sent a copy of our book to the Library of Congress. This is part of the agreement we made when we ordered and paid for a Library of Congress Control Number (LCCN). If you hope to have libraries carry your book, you must have this number.
We envision our book being carted in a crated box to be one of millions of crates in a warehouse, much like 'THAT' scene in Indiana Jones: Raiders of the Lost Ark!
