The Lost Diaries of Young Indiana Jones was a proposed series of illustrated, educational hardcover books by Donovan Publishing 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 but the project was cancelled before any books reached store shelves. Nevertheless, advertisements did appear in contemporary magazines including The Lucasfilm Fan Club Magazine.
Publisher's summary[]
At long last, the lost diaries of young Indy have been found! Here are the chronicles, artifacts, maps, clippings and souvenirs from Indiana Jones' famous first trips. Book I is packed with fascinating facts about Egypt and Arabia: pyramids, mummies, hieroglyphics, tomb robbers, bedouins, sandstorms, oases, camels, cobras, the afterlife, and much, much more.[1]
Bet there's a catch. The book is also dotted with loopholes and missing information, and it's up to the reader to solve the puzzles and mysteries. And then there's the greatest mystery of all: years ago, Indy learned of the famous lost city of El Dorado, the Land of Gold! He hid the answer throughout his diaries. But where?[1]
