I think that you misconstrue as collecting on the Kindle a completely different motivation. I have several hundred books on my Kindle. Generally they are either books that I want to read or books that I want to keep available as a reference. For example references, are, bible, koran, dhamapada, certain science texts, certain historical texts, certain complete collections(Shakespeare) or poetry books (Complete Ginsberg, Complete Creeley). Once I read a book or decide that I am no longer interested, it comes off the Kindle. If I run across a book that I am interested in reading I add it in even if I don't intend to read it immediately.

I have about 14 collections "Currently Reading (never more than 3), Spanish books, History, Biography, SF, non-fiction, fiction, fiction Asia, poetry...etc... A book may appear in more than one collection. I recently set up and put out of my mind the plug board for naming collections. I devote very little time to tinkering with books on Calibre except at the point that I add a book to the library.
