How do you keep track of the books you've finished reading?

[Jeani]

I'm trying to find a creative way to somehow mark a book I've finished reading. I would love to have control over one of the "labels" like the one that shows "New" or "Lend Me" but can't find a way to do that. Anyone have a creative way to mark a book read so that you can tell from the library page what is read and what isn't?

On my Nook Color I move my books to a shelf I created titled "Read." You could also just archive the book when you're done reading it. I'm not sure if there is a way to put a tag on the cover when you look at them in your library, though.

I use calibre and just keep the ones i have not read on my nook. If its one I have bought from bn, I just archive it.
