[Koha] Virtual bookshelves

Hello: I'm toying with the idea of setting up some kind of virtual bookshelf. The idea is that a bookshelf can be created and named, and then books can be searched for in the usual way and added to the bookshelf. I'm hoping to use this for things like printing out card and spine labels, changing subject heading entries for a group of books en masse, withdrawing discards, etc. Anybody have any thoughts on this?
