Curved structure I have provided for record collection (7)
I believe the answer is:
archive
'for record collection' is the definition.
(I've seen this before)
'curved structure i have' is the wordplay.
'curved structure' becomes 'arch' (architectural structure).
'i have' becomes 'ive' (contraction of 'I have').
'arch'+'ive'='ARCHIVE'
'provided' is the link.
(Other definitions for archive that I've seen before include "Vault" , "Historical collection of documents" , "Repository of historical records" , "Stored data" , "Depository for records and documents" .)
