Need help with archival before I decide to sell some C64 stuff.

[damcanadian]

OK, so I have come into a respectable collection of C64 stuff, some rare, some not, mostly I cant tell since its not my scene, but before I decide to sell it I wanna make sure scans of anything not available are made, where would I wanna look for this stuff to cross check what I have? on top of the boxed stuff is around 30 or so official floppies, and then the hundred+ copies.
