Dear Adem,

Janos Karpati wrote a book, in Hungarian, about Bartok's
quartets. As I knew it was translated to English, I asked for
"karpati" on http://www.amazon.com where the answer gave me
two books :

Bartok's String Quartets
by Janos Karpati
Corvina Press, Budapest, 1975
Out of print

and

Bartok's Chamber Music
by Janos Karpati
Pendragon Press, 1994

If you can find it, I'm sure it'll efficiently help you.

Best wishes, Pierre
