The idea that there was more than one transporter room on the original Enterprise originated in the book 'The Making of Star Trek', published in 1968. On page 192, it describes that there are 11 transporter rooms on the Enterprise. 4 of them are ordinary 6-person transporters, 2 of them are cargo transporters and the other 5 are 22-person transporters that are used only in emergencies.
Despite this, the TOS episodes only ever mentioned "the Transporter Room". The episodes 'The Enemy Within' and 'Wink of an Eye' very strongly implied that there was only one transporter room, although in my opinion, there are many reasons why 'Wink of an Eye' should not be considered canon.
So why did the TV episodes not acknowledge that the Enterprise had more than one transporter room, if the info came straight from the writer's guide? And are there any novels that mentioned additional transporter rooms on the Enterprise, or even the fabled 22-person transporter?
I seem to remember that the TAS episode The Lorelei Signal mentioned multiple transporter rooms and I know Franz Joseph's Star Fleet Technical Manual had pictures of all three types of transporter.
