All of our orders are sourced through Ingram, so in order for a book to appear on Bookshop.org it has to be available in Ingram's catalogue.
If you'd like to get your book listed in Ingram's catalogue, we recommend going to the following page: ingramspark.com. They should be able to help you out or point you in the right direction.
If your book is already available on Ingram, but isn't appearing on Bookshop.org, click here.
