 What does "Integration" mean?
Bookstore integration lets you display data from your local bookstore—adding availability and pricing information to every work page. It's a great way to see at a glance if a book is at your local bookstore. Read more about it in this blog post.
 How do I turn it on?
Choose which bookstores you want to display data for under Edit profile/account settings.
 How do I get my local favorite bookstore to integrate?
You can invite them to join yourself! We've got a bookstore form letter (or two) drafted, which you can use as a starting point.
More technical details on the integration program are here.
