I'm not sure why mine is so large. I store each of my books redundantly - both in AZW3 and EPUB format. But that shouldn't effect the metadata, other than maybe adding an extra entry making it known that I have both formats. Book cover art is only stored either within the book itself, or in "cover.jpg" as far as I know. I do store the "comments" that Calibre fetches for me, and three tags per book. I don't store "language". "Series" name is stored if the book is in a series.

If there is routine maintenance (cleanup) of the Calibre database that is supposed to be done - well, I'm not doing that. So something like that could be the cause as well. Who knows - different people, different books, different ways of using Calibre, different computers (I'm on Linux - maybe the database itself is entirely different).
