It would be useful to have the load more button (and also previous button) at the top of a book list. When going through read books or want to read books, these cannot be searched by name, and sorting by title can be time consuming if the books you're looking for are at the very end, since you will need to go to the bottom of the page to load the next page on the list. Easier navigation for lists would be more useful when editing many books in a list or when double checking for a specific book.
