The History of SF
Brian Ash’s The Visual Encyclopedia of Science Fiction remains a favorite of mine, as it’s the first book I read on the history of SF. Although the fat softcover spine of my childhood copy, now around 40 years old, is simply too creaky to allow any scanning of the interior...
...recently I was able to pick up an ex-library copy in hardcover. The hardcover unfortunately has no dust jacket, but the spine is solid enough that I finally was able to get some interior shots as well!
