*Science Fiction, Fantasy & Horror: Not Thirty, but three books by William Tenn, an unfairly overlooked author. These are all collections of his short stories, including one where a man unwittingly sells the whole of Earth to an alien, another where a 20th century man gets a Bild-A-Man set, yet another where the idealistic Venusians are taught about Terran culture by humans who make Sir Les Patterson seem civilised (all in The Seven Sexes) and one  where Earth is ‘liberated’ from aliens  so many times that not much is left to liberate (Of All Possible Worlds). The final book, Time In Advance, consists of four longer stories, all fizzing with ideas and energy.
