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. Currently, the list is at version 4, compiled October 2016.

The list can be consulted at the official website.

The Classics of Science Fiction lists were generated by using 65 lists published from 1949-2016 where readers, writers, editors, scholars, and librarians remembered their favorite science fiction stories. The results reflects the most common titles across the 65 lists. Read “Statistics and Math” for explanations about ranking percentages and ratios.

This particular collection reflects the list by rank.

If you feel the urge to vote for any of the books, or add missing ones – PLEASE STOP. This is not an open voting list, but rather a list made with a specific order, with a specific set of books. Thank you for understanding.

PS. You can "like" the list itself though :-)
PPS. Unfortunately, Goodreads only allows one person to add 100 books. If the second person adds any, they will have the same weight as the first person's, so I can't add the rest 39 books without messing the order of the first 100. I will leave it like that, 100 books is enough, and if you managed to go through them – feel free to check the original list.
