It's much easier just to go to the GCD and search on Kirby sorted by date, bminor.
Once you get past the "junk" entries that for some reason sort earlier than 1938, you get a pretty clear list of his work. (I think these "junk" listings are GCD entries without actual publishing date information), Plus aren't there Kirby checklists out there on-line, too? TwoMorrows did one, as did Blue Rose Press a while ago. Don't know if anyone has posted the actual listings, but how much effort are you willing to spend to duplicate what other folks have already done?
Here's the link to the GCD info:

http://www.bpib.com/illustra2/kirby.htm)
but how deeply do you want to go into the subject of listing his work? For instance, just saying "Capt. America" doesn't really do it - you have to list only issues 1-10 and even then it's deceptive as after the first issue, he's hardly there beyond layouts and a few panels here and there. The whole thing gets pretty tricky.
Best of luck, but it's best to define your parameters and also not to spend too much time and effort reinventing the wheel.
