Step 4: Determine Technical Details
Do you need to be concerned about copyright, trademark, an ISBN, EAN or UPC bar codes, Library of Congress Control Numbers (LCCN), or P-CIP data? If you plan to sell through small local retailers or are only giving your books to friends or family, these items are not necessary.
If your sights are set on a regional or national market with distribution to major retail chains and bookstores, you will find these items are necessary before buyers or distributors will purchase your books. Local or independent bookstores may or may not require these items; it’s always best to check with them first. See below for more details.
