A quick scan of the [Zefram Cochrane page][1] on [Memory Beta][2] finds references to the following books he appears in: - [*Metamorphosis*][3] (TOS episode novelization) - [*First Frontier*][4] (TOS novel) - *A Warp in Space*, Star Trek #49 (TOS comic) - [*Federation*][5] (TNG novel) - [*Imzadi*][6] (TNG novel) - [*First Contact*][7] (TNG movie novelization) - [*Honor Bound*][8] (DS9 novel) Note that I'm ignoring reference works (like the [*Star Trek: The Next Generation Technical Manual*][9]) and other books (like [*NF: Stone and Anvil*][10]) where he is mentioned but doesn't appear as a character. A scan of his [Memory Alpha page][11] and his [Wikipedia page][12] don't turn up any more, nor does a search of Google books.
