Harvard's Houghton Library has acquired "The Star Trek Guide," a publication that was distributed to Star Trek writers, and it's a hoot. "Captain would not hug pretty Yeoman on the Bridge of his vessel." Oh really? However, the curious phenomenon of fatalities of landing party members who wear red shirts is left unaddressed  ("Ensign So-and-So, go look behind that rock"). There are explanations for the term stardate and why so many Class-M planets were visited, as well as an answer to the question "Are you people on LSD?"
