I purchased a copy of Clarke's Childhood's End from my local library today. The book has a stamp in it from my local library and nothing indicating any other owners. The copy appears to be from the 1970's since the jacket information mentions Clarke's activities in the 1960's. So when was this classic of science fiction checked out?
It has sat on a shelf since 1985. Not quite as bad as a first edition of Rendezvous with Rama that had never been checked out but that's pretty bad.
