The Star Trek Concordance is a reference book by Bjo Trimble about the television series Star Trek. The first edition was self-published in 1969. A mass-market edition was published in 1976. The 1976 edition contains summaries from every episode of The Original Series and The Animated Series, as well as an encyclopedia of characters and technology from the series.
