Heh, I'm just
storing them elsewhere. Nothing too involved, just subfolders by the authors' names (last, first for me), and then sub-sub folders to keep series books together (I renamed them '01 title,' '02 title,' etc to keep the order). I did grab copies of the Connect books and catalog them similarly, changing their horrid names to something a human can read and understand.
If you don't have a big collection,
that's the best time to start cataloging them, less initial work.
