This vicar upset keeper of records (9)
I believe the answer is:
archivist
'keeper of records' is the definition.
(I've seen this before)
'this vicar upset' is the wordplay.
'upset' is an anagram indicator.
'this'+'vicar'='thisvicar'
'thisvicar' with letters rearranged gives 'ARCHIVIST'.
(Other definitions for archivist that I've seen before include "record collector" , "Library worker" , "Keeper of records" , "Record keeper" , "record holder" .)
