Very interesting piece on Khotan and Khotanese – not a peer reviewed journal article but cool nonetheless. Introduction excerpt:
Most people do not know that until about a thousand years ago, the Tarim Basin (northwest of Tibet, which is the part of Xinjiang below the Tian Shin Mountains) was Indic in culture and it was a thriving part of the Sanskritic world; its people spoke the Gāndhārī language which many see as descended from Vedic Sanskrit, and Khotanese Saka, which is also closely related to Sanskrit. Perhaps the region to compare it most is Kashmir, to whose north it lay. There was also much interaction between the two regions with many scholars traveling from Kashmir to Khotan, and silk culture is believed to have passed from Khotan to Kashmir and then into India.
