The Indycron continuity database is an internal database used by Lucasfilm which covers all forms of licensed Indiana Jones media. It is maintained by Leland Chee, keeper of the Star Wars Holocron. Says Chee, "We try to make things as consistent as possible so Indy doesn't get his hat twice or be introduced to Wu Han or Marcus Brody twice. We track things like when Indy was born, where and when he went to high school, when and where he got his college degrees, where he teaches and when, what kind of pistols does Indy use, what languages does Indy speak, and other things like that."
