Early news from a rare book sale (5,7)

Ross

I believe the answer is:

first edition

I'm a little stuck... Click here to teach me more about this clue!

'a rare book sale' is the definition.
The definition suggests a singular noun which matches the answer.

'early news' is the wordplay.
'early' becomes 'first' (associated in meaning).
'news' becomes 'edition' (I am not sure about this - if you are sure you should believe this answer much more).
'first'+'edition'='FIRST EDITION'

'from' is the link.

Can you help me to learn more?

(Other definitions for first edition that I've seen before include "Collectible book" , "Initial printing (of a book)" .)
