The Grand Comics Database (GCD) is a digital database dedicated to the exhaustive cataloging of comics. Its main function is to store detailed information about creator credits, story details, and publication data. Although it is not a physical publication, it acts as an essential reference tool for researchers and collectors. Its relevance lies in the ability to track the history of the medium through structured metadata, allowing analysis of circulation and editorial production. It is a key resource for understanding the comic industry beyond the covers.
