Episode: TOS 049 - Piece of the Action, A
A history volume left behind accidentally by the visiting crew of the U.S.S. Horizon in 2169 on Sigma Iotia II, before the development of the Federation Prime Directive of non-interference. "The Book," as the Iotians dubbed it, became revered as the new model for their society as much as any religious text.
