notation

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

'linguistic code' is the definition.
'notation' can be an answer for 'code' (thesaurus). I am not certain of the 'linguistic' bit.

'good books in ireland for one' is the wordplay.
'good books' becomes 'ot' (Old Testament).
'in' means one lot of letters goes inside another.
'ireland for one' becomes 'nation' (ireland is a kind of nation).
'ot' inserted inside 'nation' is 'NOTATION'.

'produced by' is the link.

Can you help me to learn more?
