Obtain book link before publishing on site?
I would like to include a link to my book on the book itself. The reason is because my book will be sold through word-of-mouth from people already having the book. It would be convenient for someone who comes across my book (from someone owning it) to be able to see the link, go on here, and purchase it. I wanted to add a QR code, for example, and the link on the back cover.
Can you tell me what the link will be before I upload my book? Thank you.
