It’s cheap circulating something drawing on a number of sources (8)
I believe the answer is:
pastiche
'something drawing on a number of sources' is the definition.
I can't tell whether this definition defines the answer.
'it's cheap circulating' is the wordplay.
'circulating' indicates an anagram.
'its'+'cheap'='itscheap'
'itscheap' with letters rearranged gives 'PASTICHE'.
Can you help me to learn more?
(Other definitions for pastiche that I've seen before include "Patches I assembled to work from several sources" , "Jumble" , "A work in imitation style" , "Work of art that imitates the style of other works" , "Operatic song" .)
