As information, it has its good points (3)
I believe the answer is:
gen
'as information it has its' is the definition.
I can't tell whether this defines the answer.
'good points' is the wordplay.
'good' becomes 'g' (abbreviation).
'points' becomes 'en' (compass points east and north).
'g'+'en'='GEN'
Can you help me to learn more?
(Other definitions for gen that I've seen before include "Information yielded" , "Lowdown (sl.)" , "Knowledge" , "Information (colloq.)" , "Informal information" .)
