Researching old Gaming magazines...
I am finally prying a few things out of my "One who dies with the most toys wins" SO. This includes ancient magazines like Space Gamer, White Dwarf, Computer Gaming World--and I need to know if these have any value. Heck, I even found a sack of old TV Guide new season reviews! There are old computer games, too, which I might even be able to get back into their boxes/sleeves/envelopes. This stuff is in good to excellent condition--but is it good for recycling only?
Does anyone have a guess of where I should research these to know if they're worth trying to sell on E-Bay or at AggieCon's convention?

That occurred to me, but I wanted to be sure I wasn't overlooking some great reference site I should know about!
