Cleaning House

I periodically go through moments when I feel that I need to clear out my gaming collection of books and boxed sets I'll never use. I'm in the midst of one right now, but I've so far managed to keep it in check because of three things. First, I remember all too well having disposed of almost all of my Traveller stuff in high school (in the idiotic belief that Traveller: 2300 had "superseded" it) and I don't want to find myself re-purchasing stuff later that I thought I'd never need/want again. Second, deciding just what constitutes a gaming product I'll never want again for any purpose is a tough question. I mean, I'm pretty darn sure I'll never play Unknown Armies (to cite an obvious example), but will I never want to read it again for any reason? Finally, assuming I can overcome the first two hurdles, how do I get rid of all this stuff? Selling it seems the obvious solution, but I'm a fundamentally lazy person and dealing with the hassle of packaging stuff up and shipping it to various buyers may be more trouble than just leaving it all in boxes in my garage.

So, anyone out there have any experience with this sort of "problem?" If so, what did you do about it? How did you handle the various pitfalls I've discussed above? I ask because, truly, I'd like to pare down my gaming collection considerably, but the logistics of doing so in a way I won't later regret elude me.
