Dear Karl-Stephan,

I'm not sure if somebody else might have mentioned it already but another article that may be useful is:

Qvarnström, Olle. "Haribhadra and the Beginnings of Doxography in India." In Approaches to Jaina Studies: Philosophy, Logic, Rituals and Symbols, edited by N. K. Wagle and Olle Qvarnström, 169-210. Toronto: The Centre for South Asian Studies, 1999.

I hope this helps.
