I understand that the Widener Library has a significant Tibetan collection. What's the best way to search for those items?
Widener Library's Tibetan-languge materials are searchable in both HOLLIS and HOLLIS Classic by romanization, not by Tibetan script, searching by author, title, keyword, or subject. HOLLLIS is not capable of displaying the Tibetan script. Here is an example:
Author : Bstan-ʼdzin-rgya-mtsho, Dalai Lama XIV, 1935- Title : Grub mthaʼ rin chen phreṅ baʼi bkaʼ khrid Title : Spyi-nor Goṅ-sa Skyab-mgon Chen-po mchog nas Grub mthaʼ rin chen phreṅ baʼi bkaʼ khrid gnaṅ ba bźugs so / phab sgyur źu ba po, Rnam-grwa Thub-bstan-yar-ʼphel.
