Source of info from dancer not available ahead of compliance (7)
I believe the answer is:
almanac
'source' is the definition.
(I have seen 'source of information' mean 'almanac' so perhaps 'source' could also mean 'almanac')
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for almanac that I've seen before include "Annual publication giving dates of astronomical and other events" , "issue every year" , "Annual reference book" , "Sailor's or farmer's calendar" , "Annual calendar of events" .)
