These are the lists we used to assemble the Classics of Science Fiction list. I’ve tried to provide the best URL to view the cited list. Sometimes this is the original document, and sometimes it’s another database. For books like Anatomy of Wonder, which are used by librarians for collection development, we extracted a list from its most recommended books. By the way, I highly recommend Anatomy of Wonder to anyone who loves science fiction. Neil Barron has passed away, but his magnificent work lives on. Each of the five editions are somewhat different, using a different panel of experts.
