Tiny stream and little river featured in short publication (8)
I believe the answer is:
brooklet
'tiny stream' is the definition.
(I've seen this before)
'little river featured in short publication' is the wordplay.
'little river' becomes 'r'.
'featured in' means one lot of letters goes inside another.
'short publication' becomes 'booklet' (I've seen this before).
'r' placed into 'booklet' is 'BROOKLET'.
'and' is the link.
(Other definitions for brooklet that I've seen before include "Small stream" , "Burn" , "Tiny stream" , "tiny watercourse" .)
