That is a great idea, David. From what I have read, it looks like it requires EPUB 3.0 and currently only works with later versions of iBooks on the iPad. Has this changed?

Also, I couldn’t get my document to validate in Epub 3.0 but it did fine when exported as Epub 2.0.1. ???

Either way, I changed the hyperlinks in my document to only go in one direction and that seemed to help. We are still awaiting total validation from the publisher.

Thank you again.
