Would love to have a public API for readng but don't want supporting it slowing us down when we need to change something. It's just the three of us in our spare time at the moment, so we need the agility!

I really, really like that use case too! Right now all you could do would be to create a collection of books on your profile, but would be nice to have on the book page I think.

> Could I send readers to their choice of bookseller?

We would like to refer people to libraries and indies, but these are obviously fragmented so a bit difficult. I think allowing authors to set a preferred book seller probably makes sense.
