TARDIS Handbook
From Tardis Wiki, the free Doctor Who reference
A TARDIS Handbook was an instruction book that detailed the various functions of a TARDIS. The Fourth Doctor owned one that had been specified to the Type 40 model and read from it: "when making modifications, it is extremely important to shut everything down, except that which it is not necessary to shut down". (DW: The Horns of Nimon)
