Incitements to riot primarily avoided in publications (8)
I believe the answer is:
editions
'publications' is the definition.
(edition is a kind of publication)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for editions that I've seen before include "Particular forms of published texts" , "Book published at different times" , "Repros" , "Copies of book about sedition" , "Numbers" .)
