Music CDs and books are different--Alpha by artist/author, then chrono if more than one by the artist/author. (That is...that's what I PLAN to do once I get my CDs and books out of the boxes). Movies are more difficult to group that way. There is no ONE artist, per se, to easily group by. Star? Director? Studio? How do you decide?
Regardless, any attempt to neatly organize anything will be completely undone by my kids within a day.
