The Lost Diaries of Young Indiana Jones was a proposed series of illustrated, educational hardcover books detailing Indiana Jones' adventures in The Young Indiana Jones Chronicles from a first-person perspective. The first entry, by Eric D. Weiner, was scheduled to be released in October 1994. The project was cancelled before any books reached store shelves, but advertisements did appear in contemporary magazines.
