Books given to German bloke (4)

I believe the answer is:

otto

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

'german bloke' is the definition.
The definition suggests a singular noun which matches the answer.

'books given to' is the wordplay.
'books' becomes 'OT' (Old Testament).
'given' says to put letters next to each other.
'ot'+'to'='OTTO'

Can you help me to learn more?
