The oldest surviving commentary on the Bhagavad Gita is the Advaita philosopher Adi Shankaracharya’s Bhagavad Gita Bhashya. Now the Sri Vaishnava Acharya Ramanujacharya’s Bhagavad Gita Bhashya has several subcommentaries, most prominently Vedanta Desikan’s Tatparya Chandrika, which is available in English on sadagopan.org. (It’s a series of PDF’s starting here.)
My question is, what subcommentaries on Adi Shankaracharya’s Bhagavad Gita Bhashya are available online in English? Is a translation of Anandagiri’s Tika there online, for instance?
Note that I’m looking for translations of traditional Sanskrit subcommentaries, not modern books.
