One pound raised during life's works in this list (12)
I believe the answer is:
bibliography
'works in this list' is the definition.
(a list of books)
'one pound raised during life's' is the wordplay.
I cannot quite understand how this works, but
'one' could be 'li' (I've seen this in other clues) and 'li' is found within the answer.
This explanation may well be incorrect...
(Other definitions for bibliography that I've seen before include "List of books on a subject" , "catalogue" .)
