I'm actually working on a massive Superman timeline right now!
The timeline has pretty much all the dates put in, but I recently found out my library has far more Superman comics then I thought they had. So I still have two encyclopedias, two novels, and about 5-6 new hardcover comic book collections to get through....a historian's work is never done. I guess I won't be able to do the Batman timeline until a month from now at the earliest.
As you can probably tell, I'm a big fan of DC and Marvel, plus any good independent stuff I can find. My favorite superheroes are Superman, Batman, Spider-Man, and Captain America. My favorite comic book series (if I had to pick one!) would be League of Extraordinary Gentlemen. Not only is it the ultimate crossover of every fictional character ever created, but it combines my two loves: pop culture and history!
