Publication of record learning about United States in recession (10)
I believe the answer is:
disclosure
'publication' is the definition.
(I've seen this before)
'record learning about united states in recession' is the wordplay.
'record' becomes 'disc' ('disc' can be a synonym of 'record'**).
'learning' becomes 'lore' (I've seen this before).
'about' means one lot of letters goes inside another.
'united states' becomes 'us' (abbreviation for the United States).
'in recession' says the letters should be written backwards.
'us' reversed gives 'su'.
'lore' going around 'su' is 'losure'.
'disc'+'losure'='DISCLOSURE'
'of' is the link.
(Other definitions for disclosure that I've seen before include "Act of revelation" , "Laying bare" , "Publication" , "broadcast" , "Release" .)
