The GAU collection is a join of the MSS assembled by Prof. P. M. Mehta as part of the GAU Caraka edition and translation project (6 vols, 1949), and the collection of Jivarāma Kālidāsa Śāstrī of the Rasaśāstrauṣdahālaya in Gondal (=Śrī Bhuvaneśvarī pīṭha), that was catalogued in 1960 (Biswas entry 0349, Janert ABC entry 102) and later sold by Jivarāma's son Ghanashyamji to the Government of Gujarat and relocated to GAU at Jamnagar.

Not everything has been digitized, but mainly items on ayurveda and rasaśāstra.

The interface is pretty awful, and the staff at GAU know this and are actively working on an update.

Best,
Dominik
