Papers about arrangement for sitar or recorder (7)
I believe the answer is:
diarist
'recorder' is the definition.
(I've seen this before)
'papers about arrangement for sitar' is the wordplay.
'papers' becomes 'ID' (identification papers).
'about' says the letters should be written backwards.
'arrangement for' is an anagram indicator (I've seen this in other clues).
'id' written backwards gives 'di'.
'sitar' is an anagram of 'arist'.
'di'+'arist'='DIARIST'
'or' is the link.
(Other definitions for diarist that I've seen before include "Person who keeps daily record of activities, like Samuel Pepys" , "One as Evelyn, Kilvert" , "eg Samuel Pepys" , "Keeper of daily notes" , "Pepys, for example" .)
