i want to make a smart collection of books that i haven't rated yet, but i can't figure out what the setting should be. i've tried setting rating is less than 1 and rating is equal to zero, but that eliminates all entries. in itunes collections, the star dialog is defaulted when making smart playlists by rating.
You want to set the criteria for the smart collection to the following:
My Rating is [blank stars]
That'll give you a collection with all the entries that don't have a star rating.
