Dorothy hoards old record in storage site (5)
I believe the answer is:
depot
'storage site' is the definition.
(I've seen this before)
'dorothy hoards old record' is the wordplay.
'dorothy' becomes 'dot' (nickname for someone called Dorothy).
'hoards' indicates putting letters inside (hoard can mean to contain).
'old record' becomes 'EP' (abbreviation for extended play record).
'dot' placed around 'ep' is 'DEPOT'.
'in' acts as a link.
(Other definitions for depot that I've seen before include "Bus station in the US" , "Store for large quantities" , "Storage base" , "Regimental HQ" , "Headquarters - storehouse" .)
