Back in October, when I was first speculating about Infinite Crisis, I posted a list of links about the first issue of that series. In that same post, I gave a bunch of links to essays by a fellow named Alan Kistler, who is one of the people blogging at Monitor Duty. Mr. Kistler had written a bunch of excellent essays about the original Crisis on Infinite Earths, which I recommended for people who needed to be brought up to speed.
Mr. Kistler has also written quite a few essays detailing the histories of various DC comics characters. I am delighted to see that thanks to my recommendation, he's created a webpage, Alan Kistler's List, which links to all of his essays. His essays include profiles of Aquaman, Braniac, Donna Troy, the Flash, Green Lantern, Hawkman, Martian Manhunter, Power Girl, Superman, and General Zod, and he plans to add other profiles soon.
The essays are great for people who want to be reminded about their favorite characters. They're also great for people who are less intense about comic books but whose husbands keep badgering them to learn more. Not that I'm speaking from experience or anything. :-)
I cannot recommend the essays highly enough. Go read.
(And nag him about getting that Firestorm essay done. I want to read it.)
