Information about category of literature or art (5)
I believe the answer is:
genre
'art' is the definition.
(I know that genre is a type of art)
'information about' is the wordplay.
'information' becomes 'gen' (gen can informally mean information).
'about' becomes 're' ('re' means regarding or about).
'gen'+'re'='GENRE'
'category of literature or' acts as a link.
This may not be correct. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for genre that I've seen before include "Artistic or literary category" , "Style/category of art" , "Literary type, species" , "expressive style of music" , "Style of work" .)
