'we recalled published unused books lacking complete clarity' is the definition.
I can't judge whether this defines the answer.

'we recalled published unused books' is the wordplay.
I cannot really understand how this works, but
'published' could be 'ran' (as in a newspaper running a story) and 'ran' is present in the answer.
'books' could be 'nt' (abbreviation for New Testament) and 'nt' is present in the answer.
This explanation may well be incorrect...
