proverbs

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

'book' is the definition.
(I know that Proverbs is a book)

'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' is an insertion indicator.
'extremely short' becomes 'ver' (I've seen this in other clues).
'probs' placed around 'ver' is 'PROVERBS'.

Can you help me to learn more?

(Other definitions for proverbs that I've seen before include "Truthful expressions" , "Book of the Bible" , "Old Testament book ascribed to Solomon, or well-known sayings" , "More than one saw" , "Adages, saws" .)
