The Encyclopedia of Science Fiction

Theme Entries from the First Edition

This is scanned from the "Checklist of Themes" in the front matter of The Encyclopedia of Science Fiction (1979). Three entries, here marked with asterisks and coloured red, were not carried over to the second edition of 1993. Two of these were reinstated for the third edition online: Weather Control (now much expanded) and SF Overtaken by Events (as Malachronism). Note that this list does not include the many shorter "terminology" entries like Ansible, Antigravity, Antimatter, etc.
