#### BUGS (next-47)

BUG-42:     can add a sub_book_num for a series that has already been taken (or is invalid, e.g. 9999) -- DB does not enforce either

BUG-45:     create a new book, fail (say for now year), and it loses the series you already set in the new html

BUG-46:     search (and really all books.html usage), don't deal with sub books and/or series ordering.  Probably should at least do subs ordering 
            (so the code I wrote for author/<id>/books) and use that for search for example
                - test with search for 'dune'
                - also test with authors book list for frank herbert

BUG-47:     books on shelf ordering is not working (prod data only?)

BUG-48:     all books only have 'remove sub book' button, no more add, and it should not be there unless you are a sub book
            - first part fixed (the right button now appears), none of the sub-book adding with a series seems to work
