The Classics of Science Fiction list, compiled by James Wallace Harris and Michael Jorgensen, is an attempt to create a definitive list of the best Science Fiction books. Harris and Jorgensen collected 65 SF book recommendation lists and generated a cumulative list of books that included any title that was on at least 10 of those lists. The result is a ranked list of 139 books.
