SRA Pilot Library 2C, 1962, #39, Walter B. Hendrickson, Jr. Space Travel. Illus. by Stephen Perry.
Yes it is an SRA Reader! Back there in the days of where we walked to school both ways uphill through the asteroid showers we learned to read with SRA (Science Research Associates). These readers were extreme abridgments of books. I think the idea was interesting reading for the classroom but the real memory is being sent up to the box of readers and trying to pick something out.
The book itself focused on conditions found in space and how men would survive there.
Here to our memories of adventures in reading!
