Many thanks to Birgit Kellner for answering my request.
Dear friends,
I would be most grateful if any among you might be able to send me a pdf of the late
Muni Jambuvijaya's contribution to: K. Bruhn & A. Wezler, eds., Studien zum Jainismus und Buddhismus (Alt- und Neu-Indische Studien 23), Wiesbanden: Franz Steiner, 1981, pp. 129-149. The article, on Buddhist citations in Jain works, is in Sanskrit or Hindi, I believe.
with thanks in advance,
Matthew
