The "Crip Books of Knowledge" refers to a variety of fictional Internet based pieces about the history of the Crip gang. The origin of the information shared in these books is unknown and the information is inaccurate.
Specifically, these books synthesize and confuse information including history, symbols, and literature of the Crips and the Folks Nation Alliance. The Crips and the Folks Nation are not affiliated in any way. In Kansas City, Missouri, the two gangs have an understanding to share territory. This isolated situation may have led some to believe that they operated together. The books' popularity spread through those merely interested in joining the Crips rather than actual members.
