Look always to keep dry dictionary? (9)
I believe the answer is:
gazetteer
'dictionary?' is the definition.
(gazetteer is a kind of dictionary)
'look always to keep dry' is the wordplay.
'look' becomes 'gaze' (gaze is a kind of look**).
'always' becomes 'eer' (poetic way of saying ever).
'to keep' means one lot of letters goes inside another.
'dry' becomes 'tt' (abbreviation for teetotal).
'gaze'+'eer'='gazeeer'
'gazeeer' placed around 'tt' is 'GAZETTEER'.
(Other definitions for gazetteer that I've seen before include "Geographical guide" , "places booked" , "Geographical dictionary" , "Book of place names" , "Geographical reference" .)
