Miscellaneous Tibetan manuscripts, including meditation and ritual texts, as well as medical and astronomical manuscripts. The principal acquisitions are:
- manuscripts obtained by Captain Samuel Turner of the East India Company when on a mission to the Panchen Lama in 1783-4, including correspondence relating to the mission, and notes on the Tibetan language
- 102 manuscripts and block-books collected in the Indian Himalayas by German explorers Adolf, Hermann and Robert Schlagintweit
- 131 volumes collected by Lieutenant Colonel Augustine Waddell, medical officer to the Younghusband Expedition of 1904. The collection includes two volumes of a manuscript prepared in the monastery of Shel-dkar in Southern Tibet (MSS. Tibet a. 15 (R), 23 (R)), which is important because of the part it plays in the history of the transmission of the Tibetan canon. The collection was split by the Indian government, and parts of it are kept by the British Library and Cambridge University Library
- Tibetan manuscripts bequeathed by W.Y. Evans-Wentz in 1965.
