 * author,series, etc. do not have explicit ordering like sub-books... sort of irritating / needs code and DB fix
 	* add/remove authors, and after save they are ordered by author.id, not order of addition (prob. needs book_author_link to have an auth_num)
 * if you remove a series from a book, it won't appear in the series drop-down if it is the first 'missing' book in that series -- either reset the list, or show all series always?
+
+* if you add a sub-book, then fail to validate (say no genre), then it takes you back, you click a genre (BUT it has lost th eparent association), so it adds a book, not a sub-book
