ezra pound

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

'writer's book not a' is the definition.
I know nothing about this answer so I can't judge whether this works.

'lot of money' is the wordplay.
'lot of' becomes 'ezra' (I can't justify this - if you can you should give a lot more credence to this answer).
'money' becomes 'pound' (pound sterling).
'ezra'+'pound'='EZRA POUND'

Can you help me to learn more?

(Another definition for ezra pound that I've seen is " American poet".)

I've seen this clue in The Guardian.
