From page 56:

"Material that many users would consider “fiction” are
nevertheless categorized in this bibliography under the
subject areas to which they putatively pertain. Material
regarding unidentified flying objects (UFOs) and subjects
such as alien “bases” in the Grand Canyon are listed in
PART 2 . Material about putative ancient Egyptian
relics in the canyon are listed in PART 16 (Archaeology)."
