When I was 14 years old, between 1976 and 1977, I was in the hospital for a serious injury. While there I was given a gift of an anthology of Star Trek short stories. I can remember some of the cover but, big surprise, that part that I do remember is a picture of the USS Enterprise. I know, how uncommon. What I remember, in particular, of one of the stories is that, like many, someone, Kirk in this case, had been stranded at some point in the past - 20th century Earth. He had been committed to a mental institution and the orderlies had nicknamed him "Superman" for his great strenght - He was apparently often violent.
Does anyone have a handle on the name of that anthology? I do remember enjoying it a great deal and it would be great to read it again if it's available.
