Geoffrey McKinney, creator of Carcosa, started threads at both the OD&D Discussion forums and on Dragonsfoot in which he listed and posted images of his entire RPG collection, which he's radically whittled down to a handful of books he finds both useful and inspirational to his gaming. I have to admit that I've often considered doing such a thing myself, as I have approximately two full bookcases of gaming products, most of them unused most of the time. Unfortunately, my resolve to get rid of many of these books is weakened by the painful memory of re-acquiring my Traveller collection after having sold it shortly before I graduated from high school, in the false belief that I'd never play it again. Likewise, I often need to know little bits of trivia associated with this or that game book and, since PDFs aren't available for most of them, I hesitate to get rid of them.
Still, I have to admit there is something very appealing about getting rid of the dozens of books I own and truly will never look at or use again, such as many D20 books or my Ars Magica collection. Of course, finding a good way to get rid of them all is the problem. I hate selling things through eBay if I can avoid it. Worse, I hate trying to come up with fair prices for these days. I figure, if I'm going to take the time to sell them off, I might as well make some money off of them, but, at the same time, how much are they really worth, especially since I wouldn't be selling off anything particularly rare or valuable?
I'll have to give this one some thought.
