File X (1)

Earth Factor X (1978 edition; title changed in ’76), by A.E. Van Vogt.

Originally published in 1974 as The Secret Galactics. In my eccentric periodization scheme, “midcentury” lasts through the end of the Sixties (1964-73), so I’m cheating a little by including this title. But I love the cover illustration.

Bonus: More editions, below.

1976 edition

1977 edition

First in a series of ten posts showcasing my collection of midcentury paperback books the titles of which include a free-standing letter “X.”

  1. What a great idea for a collection! Thanks for sharing, Josh. I love seeing how other people develop their collections. I tend to pick up sci-fi novels with “bubble headed” astronauts on the covers. Now I might need to start looking for some X titles!
