Leaflets, booklets (9)
I believe the answer is:
pamphlets
This clue is a double definition.
'leaflets' is the first definition.
('pamphlet' can be a synonym of 'leaflet')
'booklets' is the second definition.
('pamphlet' can be a synonym of 'booklet')
(Other definitions for pamphlets that I've seen before include "Brochures" , "Tracts" , "Small booklets" .)
