I got (stole...) the idea from Anthony Boucher, that is correct. Lots of great old stories from Weird Tales and others occasionally were made available in anthologies. I devote way too much time rummaging through old book bins and second hand shops trying to find said anthologies.
Just read another great story the other night called 'The Jumpity-Jim', not sure of the author off hand but it will for sure make an apperance in Strange Aeons in the near future...
