Calibre is a nice (and free!) tool for cataloging collections of ebooks. Lately I've been using it to organize a bunch of titles to load on my Amazon Fire tablet for reading.

The big think to keep in mind with Calibre is that updating the metadata doesn't update the actual book files, instead the metadata is stored in its own Calibre library file. If you update the metadata for a book then copy just the book files to a different location then the metadata doesn't copy with it, you need to either use Calibre to copy the book to a device or to copy the Calibre library.
