And now for something you'll really like:
DC Comics Official Site. Visit the webpage of the company that took a chance on Blue Devil and saw it through 31 issues.
The Earth-One Index: Blue Devil. Too...lazy...to...annotate.
eBay. If you don't own any issues of BLUE DEVIL, yourself, I'd highly recommend you get your butt over to ebay and see what they've got.
The 5 Earths Project. To be perfectly honest, I'm not sure what these guys are all about. I stumbled across the site in Google and searched it for "Blue Devil". Lo and behold people have actually written fan fiction about him. Besides me, I mean. Looks to be in-continuity stuff. But don't quote me on that.
Greatest Comic Book Creators of All Time. Designed by my old college roommate and all-around swell guy, Donald Pfeffer. Please note this is currently a work in progress.
The Nuclear Fan, The Unofficial Site for Firestorm, the Nuclear Man. Or as George W. would say, the "Nukular Man". Devoted to an occassional friend of the Blue Devil, this is a fairly nice, clean-looking site with a good news section. Hopefully the author will continue to fill out the biographies and such.
The Unofficial DC Comics Index Series. A DC Chronology project that is very thorough.
The Unofficial Green Lantern Corps Web Page. If you looked up exhaustive in the dictionary...
Four Color Explosion. This is a comic review site run by Randy Jackson, a cool cat you'll occasionally run across on Usenet, and a guy who was kind enough to put a link to my Blue Devil site on his own links page.
