Don't buy these books!
Alphascript has begun publishing Star Trek-related books. Do not buy them. Alphascript's business model is simple: the content is swiped from wikipedia, and the cost is justified on the grounds that these are print-on-demand books (though Lulu-style POD books can be very reasonably priced). This is the same outfit behind that hundred dollar thesis reprint I mentioned a few posts back.
They have a 168-page book called Star Trek: The Original Series: List of Star Trek: The Original Series episodes, Theme from Star Trek, List of Star Trek: The Original Series writers, Cultural influence of Star Trek, Star Trek. Price: $72. A 236-page book called Star Trek: Gene Roddenberry, Fictional universe, Star Trek: The Original Series, Technology, NBC, Where No Man Has Gone Before, Star Trek: The Animated Series. Price: $94. They're doing similar books for other TV series, including Doctor Who (in fact, I first heard about the Who books over at Gallifrey Base, then checked for Trek stuff.)
