ABANDONED. Science fiction from the 50s or 60s about who/what lives on various planets

Had a used paperback copy of it in the 70s, aimed at adult readers, written as if factual but was really speculative fiction.

Barlowe's Guide to Extraterrestrials? Barlowe's Guide to Extraterrestrials: Great Aliens from Science Fiction Literature

[JB]

Thank you for the reply, but no, that's not it. Am quite certain it was from the 50s or 60s and Barlowe's Guide to Extraterrestrials doesn't match that.

JB, are you still looking for this or did you find it?
