After publication, clear drawer (6)
I believe the answer is:
magnet
'drawer' is the definition.
(I've seen this before)
'after publication clear' is the wordplay.
'after' means one lot of letters go next to another.
'publication' becomes 'mag' (abbreviation for magazine).
'clear' becomes 'net' (as in net profit).
'mag' next to 'net' is 'MAGNET'.
(Other definitions for magnet that I've seen before include "Lodestone, for example" , "Powerful attractor" , "it could be a draw?" , "Something attractive" , "Drawing influence?" .)
