And Anohter Thing... I left out a nod to Keltner's Index, one of the forerunners of the Golden Age. I printed Keltner's notes out years ago and I still have it. I've always been an indexer at heart. I have all the Olshevsky indexes (minus Conan, who is not really a Marvel product, I digress...) and I used to make Post-It notes when I found an error. Now I feel like I can throw out my Olshevsky Indexes and my Keltner as we have all that data, and more, here.

Do you ever find an error from the Olshevsky Index? He was great about noting that there were errors when he was publishing in the 70's and 80's. Now, with this community, we can compare notes immediately. That is another a great resource we have and something that makes this site great. The linking to Grand Comics Database is also good. That is a great site also, but this one, with it's links, graphics, and editors is, in my humble opinion, better.
