Alien Compendium
This guide lists 268 types of being and 75 types of craft that witnesses, contactees and folklore have described. It runs from the Greys of abduction reports to ancient watchers, and from the flying saucer to the Tic Tac.
Every entry is a reported or claimed type. None is a confirmed finding. We note where each description first appeared, how many witnesses stand behind it, and how much of it comes from fiction or folklore. For cases with documents behind them, see the declassified PURSUE files and the UFO case archive.
