To arrive at a rough guess of the popularity of all original Star Trek novels to date, I began with Wikipedia’s list of Star Trek novels, and I built Goodreads shelves for original novels related to each of the Star Trek TV series and one shelf for crossover/miscellaneous original fiction titles, separating out adaptations and young adult novels onto their own shelves as well. Then, I calculated the cube of the current rating for each novel (expressed as a percentage) times the log of the number of folks rating the novel, resulting in the rankings below. As usual, I’ve eliminated the Goodreads data, leaving only the orderings. YMMV.
