I have now completed epub versions of The Old Testament, The New Testament, The Book of Mormon, The Pearl of Great Price, and The Doctrine and Covenants in html and epub versions which are suitable for navigation on ereaders without the Touch Screen capability (my Sony PRS300 eReader, for example). The current versions include:
1. Two-layer navigation index (Book...Genesist) and (Chapter)
2. Because some of these devices are slow to move around in, I found it useful to include the Book name in each Chapter Heading...thus, when you open any chapter in a given book, you get 2 Nephi Chap 3 (example only).
3. I also kept the books separate as it seemed to improve navigation speed (am guessing it is due to dumping and loading internal memory).
Please feel free to use these resources at no cost.
I am not trying to compete with the Church's recent release. I just haven't been able to get the new release to load with good navigation control on my device. Options are always good, yes? This effort took me too much time not to share.
