Google Books

Thomas mentioned Google Books in a recent podcast, and how it’s a good idea to have our books on them so AI search engines can find them. I barely knew Google Books was a thing, so obviously I haven’t done that yet. :P Is this something anyone else has experience with?

My books are on KDP, so I don’t want to sell through Google Books. But could I upload a sample of each book with the Google book ID? Or is there a way to link books on Amazon to Google Books?
