I've tried deleting the book, including on the iPad and the Macintosh with attached iTunes. This was not easy because iTunes stores a file in it's music repository and in the iTunes database, but I did it successfully. I then redownloaded the book and changed the name, just to be sure. Still no cover art. BTW, adobe acrobat on the desktop Macintosh shows the cover art. All other O'Reilly ebooks display just fine.
Any help you could offer would be appreciated.
