Frances W. Pritchett
Frances W. Pritchett, Professor Emerita, at Middle Eastern, South Asian, and African Studies, Columbia University, has been maintaining for close to two decades now a website dedicated to “Columbia’s most influential PhD”. The interface is dated but it contains some remarkable material: notably an extensively annotated version of Annihilation of Caste and the unpublished Preface of The Buddha and His Dhamma.

The Ambedkar International Center, USA has recently developed a multi-lingual online searchable site containing the volumes of Bahasaheb Ambedkar: Writings and Speeches. The languages supported are English, Marathi, Gujarati, and Hindi. They are also doing useful translations of some Marathi articles by Ambedkar into English (see here and here). They are active on X (formerly Twitter). All cross-references to BAWS included in my posts are to this site.
