Concerning writing of artistic value (8)
I believe the answer is:
literary
'concerning writing of artistic value' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for literary that I've seen before include "To do with books, poems etc" , "Type of writing of artistic merit" , "Of or concerned with good books and writing" , "Indicates writing of artistic value" , "Relating to good creative writing" .)
