Locate collection of books including nothing by Proust (6)
I believe the answer is:
orient
'locate' is the definition.
(I've seen this in another clue)
'collection of books including nothing by proust' is the wordplay.
I cannot really understand how this works, but
'of' could be 'o' and 'o' is present in the answer.
'books' could be 'nt' (New Testament) and 'nt' is found within the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for orient that I've seen before include "London team" , "Rising earlier" , "Align; eastern" , "Adjust to surroundings" , "Determine (one's position) with reference to another point" .)
