This is one of about 100 vintage science fiction paperbacks from the 1960s and 1970s that my husband received as a very generous gift from a family friend. Right now we're in the midst of cataloging them all on LibraryThing.com. If you're on LibraryThing you can find our collection here! It's been really fun to take a look at all these books, many of them anthologies and many of them classics of the genre. Jeff has even been dipping into a few and reading them!
