Spell book contents

I can search within the game on a huge range of subjects, including all available spells--but there's no listing of what spell book a given spell belongs to, and no entries for each spell book, complete with all the spells listed in it.  Would seem to be a natural, so you can find at once what spells will be available on the next level of a given element if a champion or sovereign chooses to take that as a reward upon leveling.
