The Best Science Fiction Books According to Readers of the Guardian

On May 16, 2011, the Guardian asked its readers to name the best science fiction novels and provide a rationale for each selection, and the results were released 10 days later: The best science fiction books | Books | The list contains hundreds of titles and series, and each suggestion is supported by a rationalization by the commenter. There are certainly many titles that I recognize, but there are an equal number of works that were unknown to me and that I will have to look at in the future.
