I'm trying to locate an anthology of international science fiction/fantasy anthology from the 1960s or 1970s.
As I remember, it included Borges' "The Library of Babel".
Another story was about a man who went for a walk and his head fell off, and the story is how he managed to climb back up his body to get his head back on.
I believe this anthology also had a story about a man taking a series of escalators down for miles and miles until he arrives at the lowest level to find the up escalator is out of order.
Searching on the publication history of the Borges' story hasn't turned up anything. Do any of these stories sound familiar?
