Case question

[Zuko]

It is a bit random for my first post, I know, so apologies, but I have put aside my serbian study while in another country and simple things are disappearing so fast...

What case do I use to say 'by', as in "Do you have books by Zuko Dzumhur", for example? Genitive I guess, as it is sort of possession?

Imate li knjige... 'Books' is in acc. pl.

Thanks

Yes, genitive. Imate li knjige Zuka Dzumhura

Welcome, btw
