One of the good books scattered around the Vatican (6)
I believe the answer is:
romans
'one of the good books' is the definition.
The answer and definition can be both related to communication as well as being plural nouns.
Maybe there's an association between them I don't understand?
'scattered around the vatican' is the wordplay.
'scattered' becomes 'strown' (I've seen this before).
'around' means to look at the middle letters.
'the vatican' becomes 'mans' (I can't explain this - if you can you should believe this answer much more).
The middle of 'strown' is 'ro'.
'ro'+'mans'='ROMANS'
Can you help me to learn more?
(Other definitions for romans that I've seen before include "Citizens of Italian capital" , "'Friends, . . . . . ., countrymen, lend me your ears' (Julius Caesar)" , "Classical Italians" , "New Testament book" , "Empire builders" .)
