Look in the yellow pages (3)

I believe the answer is:

eye

'look' is the definition.
(I know that eye is a more specific form of the action look)

'in the yellow pages' is the wordplay.
'in' indicates a hidden word.
'EYE' is hidden in the letters of 'the yellow pages'.

(Other definitions for eye that I've seen before include "Look at, scrutinise" , "Oculus" , "Dark spot on a potato" , "Glance" , "Needle or lace hole" .)

I've seen this clue in The Irish Independent.
