AbeBooks: 50 Essential Science Fiction Books: This was a virtually impossible task. Put together a list of 50 must-read science fiction books and don’t make anyone angry. Science fiction is the most discussed and argued over genre in literature but it actually goes way beyond books and into film, TV, video games and even toys.
Here are the criteria I used. One book per author, so that was hard on the big three of science fiction – Robert Heinlein, Isaac Asimov and Arthur C Clarke, who each have multiple classic titles to their name. Attempt to show as many sub-genres of science fiction and plot themes as possible. Include early stories that influenced the genre as a whole and launched popular themes, even if those books appear a bit dated today.
