Best Books Publishing & Distribution had a booth. I couldn't find them online. (If anyone has a link, let me know .) They had an amazing two-volume set of books with CDs called We Believe. A 1525-page reference book by Rulon T. Burton, organized alphabetically by topic. I was impressed.
Newcomer Greenjacket Books had a small booth. They five titles out and will be releasing more this fall. They seem to cover the gamut from fiction to non-fiction.
Signature Books , known for books on Mormon history and the Rocky Mountains, had a display of their newer releases and bestsellers.
If you have LDSBA photos to share, e-mail them to me and I'll post them.
