This is my biggest issue: discoverability.
The site has an index which shows 12 books at a time, and it looks like 36 pages. So roughly 430 books.
This is not actually a gigantic number of books, one that is small enough that it would be great to look through all the books, and yet I'm never going to do that if I have to page through 12 results at a time.
It would be great to get a simple list view of the collection.
