Crossword Genius

Reserved one volume for the editor (6)

Ross

I believe the answer is:

booked

'reserved' is the definition.
('book' can be a synonym of 'reserve')

'one volume for the editor' is the wordplay.
'one volume' becomes 'book' (book is a kind of volume).
'for' means one lot of letters go next to another.
'the editor' becomes 'ed' (abbreviation).
'book'+'ed'='BOOKED'

(Other definitions for booked that I've seen before include "Reserved in literary way?" , "Reserved, bought ticket in advance" , "Reserved, arranged say seat in advance" .)

I've seen this clue in the Evening Standard.
