Classics of Science Fiction Books and Classics of Science Fiction Short Stories identify the books and short stories that are most remembered based on how often they are cited by awards, best-of-lists, polls, editors, scholars, and other sources of recognition.

A minimum number of citations are required for works to be included in our classics lists. Books (novels, anthologies, and collections) are required to have at least twelve citations; short stories must have at least eight.

You can use the List Builder to configure your own lists. You can also view the citation sources used for books and short stories. The classics lists can be re-sorted by clicking on any column heading.
