That's a good definition.
It doesn't help me much with a list, though, because I don't reread very often, for some reason.

Books I do know I reread a lot:

_The Odyssey_, Homer(?)
_Howl's Moving Castle_, Diana Wynne Jones
_Dogsbody_, Diana Wynne Jones
lots of other stuff by Diana Wynne Jones
_The Luck of Brin's Five_, Cherry Wilder
_The Song of Mavin Manyshaped_, Sheri S. Tepper
_The Anubis Gates_, Tim Powers
most anything by Terry Pratchett
_A Morbid Taste For Bones_, Ellis Peters
_The Dark Knight Returns_, Frank Miller (as soon as I finished reading it for the first time, I went straight back to the beginning and started again)

> The Ladies of Mandrigyn (a heroic fantasy thing whose author I can't remember)

Barbara Hambly, another of my favourite authors.
_Stranger at the Wedding_ is my most-reread Hambly novel, but _The Ladies of Mandrigyn_ is near the top of the list.
