'book' is the definition.
(I've seen this before)

'issues about extremely short' is the wordplay.
'issues' becomes 'probs' (I can't explain this - if you can you should believe this answer much more).
'about' indicates putting letters inside.
'extremely short' becomes 'ver' (I've seen this in other clues).
'probs' enclosing 'ver' is 'PROVERBS'.
