If you collect comic books, you probably already know about the
Grand Comic Book Database, but in case you don't, you should certainly check it out. The goal of the GCBDB is to catalog all the comics ever made. I've made a whole lot of searches, and it seems like they are about 90% complete in that task. They have a small and medium size scan of each cover, and they list the cover artists. They list the creators of each story inside, including script, pencils, inks, colors and letters. They list the genre, characters, a plot synopsis of each story, and where the story was reprinted, or reprinted from. They list the cover price and on sale date. They list know variations. There are also notes, and those can be the most interesting thing.
This is an incredible resource! The Overstreet Price guide lists only a tiny bit of this information. They usually center on a small list of artists that they consider "Collectable", and ignore many noteworthy artists.
When I am looking over a run of comics these days, I invariably consult the GCBDB. There is always a wealth of interesting information there. I always learn something new when I check the GCBDB. Of course this slows down my work as I just have to check out some of the stuff they mention!

As a random example, here's some interesting info I found when doing a search of the relatively obscure 1970s series "Marvel Premiere". It was interesting to me, at least! Maybe it will be interesting to you, too.
Issue #2, Phil Kane, a character from a 1956 Jack Kirby Yellow Claw reprint was retouched to be Nick Fury! (This I 'gotta see!)
Issue #15 Although uncredited, Klaus Janson certainly inked at least pages #8-11.
Issue #24 The Marvel softball team appears on pages 15-17 of this issue, with Marie Severin providing most of the likenesses. Chris Claremont, Len and Glynis Wein, Marv Wolfman, Tony Isabella, Irene Vartanoff, Herb Trimpe, Mark Hanerfeld, Bill Mantlo, Mike Kaluta, and Al Milgrom are featured. See the letters page to Iron Fist #2 for more information.
Issue #50 Letters page article on making this issue including the credits and a photo of Roger Stern, Jim Salicrup, and Alice Cooper.
Issue #53 Cover is by Frank Miller and Joe Rubinstein . (I didn't know that!)
Issue #54 Another Frank Miller cover!

I'm sure that there are numerous errors and omissions on the database, but people can submit corrections and cover scans when needed. It's just going to get better and better. This is a really great resource. It's one of the many things that make's one thankful for the internet.
