Publish again (7)
I believe the answer is:
reissue
'publish again' is the definition.
('issue' can be a synonym for 'publish' so perhaps 'reissue' is OK for 'publish again')
This is the entire clue.
(Other definitions for reissue that I've seen before include "get book brought out again" , "Publication reprint" , "Republish" , "A second impression, perhaps" , "Send out again" .)
