@@ -8,3 +8,8 @@ BUG-46:     search (and really all books.html usage), don't deal with sub books
             (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
