A collection of articles from the 1970s fanzine Best of Trek, this book is a snapshot into the Star Trek fandom of the era, with speculative "faction" (writing that speculates on, say, Klingon society, using what we already know to be true), Star Trek trivia, letters from fans, and articles on topics from time travel paradoxes to the best episodes of The Animated Series. While some of the episodes and letters feel random to a modern Trek fan (the series of letters debating Space: 1999 is a good example), it's an interesting window into what fans were thinking and doing, and the range of fandom interests.
