Robots, nudes and spaceships, …

… SF is more than that.

Science Fiction (often called sci-fi or SF) is a popular genre of fiction in which the narrative world differs from our own present or historical reality in at least one significant way. This difference may be technological, physical, historical, sociological, philosophical, metaphysical, etc, but not magical (see Fantasy).

Science Fiction books from before the 20th century are listed on the page Precursors of Science Fiction. The cutoff is more by author than by date. Jules Verne (1828-1905) is usually considered the first modern SF author.
Feel free to add reviews of books to the page.
