The Grand Comics Database (GCD) is an Internet-based project to build a database of comic book information through user contributions. The GCD project catalogues information on creator credits, story details, reprints, and other information useful to the comic book reader, comic collector, fan, and scholar. The GCD is a 501(c)(3) nonprofit organization incorporated in Arkansas. History One of the earliest published catalogues of comic books appeared in the 1960s, when Dr. Jerry Bails and Howard Keltner put together some projects to catalogue the comic books of the "Golden Age." These efforts were Dr. Bails' The Collector's Guide to the First Heroic Age of Comics, and Howard Keltner's Index to Golden Age Comic Books, and their collaboration on The Authoritative Index to DC Comics. The next big step in organizing data about comic books was Robert Overstreet's Overstreet Comic Book Price Guide, which is still being published. This guide is sometimes referred to as the first best attempt to list factual information beyond the superhero comics. It was likely the first catalogue to get widespread distribution. Today there are several other comic book price guides. In 1978, the GCD's immediate predecessor, APA-I (Amateur Press Alliance for Indexing) was formed by a few fans who were interested in exchanging information on comic books in index form. These people were generally interested in either one of two things — either following the plot threads and continuity of the stories, or the creator credits. APA-I is also still running, as a paper-based index. The organization publishes a quarterly magazine. APA-I members have gathered editorial records and conducted interviews with comic book professionals, to add to the information that could be gleaned from the books themselves. In late 1993 and early 1994, three members of APA-I interested in comic books started up an e-mail correspondence. Tim Stroup, Bob Klein, and Jonathan E. Ingersoll soon began sharing indexing information in a common format using electronic media for storage and distribution. By March 1994, they had formed a new group to create an electronic version of APA-I related to comic books, giving it the name Grand Comic-Book Database and the goal to 'contain information on every comic book ever published'. The newly formed GCD grew slowly, using the new medium of e-mail to canvass friends and acquaintances from APA-I as well as other contacts in comics fandom. Early work consisted of indexing information, setting goals, and deciding
