It is a seemingly impossible feat. In fact I haven't been able to make it work the way I'd like. All my book chapters are listed alphabetically with no care to the actual book at all - or sorted alphabetically by the first sentence in the chapters. Anyways, it's a real pain to listen to on my old school iPod.
That is until I used the search function under music. Even though my books are listed as audiobooks, the search will find them BY BOOK TITLE. It might help that I have sorting set to album and the album set to be the book title... but there ya go.
