Most of literary works getting advance publicity (7)
I believe the answer is:
trailer
'advance publicity' is the definition.
(I've seen this before)
'most of literary works' is the wordplay.
'most of' means to remove the last letter.
'works' indicates an anagram (work can mean to twist or convulse).
'literary' with its final letter taken away is 'literar'.
'literar' with letters rearranged gives 'TRAILER'.
'getting' acts as a link.
(Other definitions for trailer that I've seen before include "vehicle without power" , "Not a leading form" , "farm vehicle" , "house on wheels" , "Short film advertising programme" .)
