Renowned editor after new books (5)
I believe the answer is:
noted
'renowned' is the definition.
('noted' can be a synonym of 'renowned')
'editor after new books' is the wordplay.
'editor' becomes 'ed'.
'after' says to put letters next to each other.
'new' becomes 'n'.
'books' becomes 'ot' (Old Testament).
'n'+'ot'='not'
'ed' put after 'not' is 'NOTED'.
(Other definitions for noted that I've seen before include "Recorded; famous" , "Celebrity" , "Observed or took account of" , "Famous or eminent" , "Having renown" .)
