Dear Prof. Rocher,

I do not know if the catalogs listed in Janert's Annotated Bibliography of the Catalogues of Indian Manuscripts (nos. 150, 261-262 and 288-290) and in Biswas'Bibliographic Survey of Indian Manuscript Catalogues (nos. 0827-0828 and 0945-0947) are comprehensive, but maybe the might be helpful (maybe also the article by The Central Asian Manuscript Collection of the St. Petersburg Branch of the Institute of Oriental Studies of the Russian Academy of Sciences by M. I. Vorobyova Desyatovskaya and Jan Nattier).
