Obtain from a variety of sources (4)
I believe the answer is:
cull
'obtain from a variety of sources' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for cull that I've seen before include "Gather - slaughter" , "Pick; select worst (for killing)" , "Gather selectively" , "Select to kill to lower numbers" , "Reduce size of herd by killing superfluous members" .)
