Stories appearing in American anthologies (3)
I believe the answer is:
ana
'stories' is the definition.
(suffix in words like Shaksperiana)
'in american anthologies' is the wordplay.
'in' says the answer is hidden in the clue.
'ANA' is hidden within 'american anthologies'.
'appearing' acts as a link.
(Other definitions for ana that I've seen before include "in equal quantities" , "literary collection" , "literary gossip" .)
