The vast expansion of Indian culture by Buddhists who penetrated through Bactria into the region of modern Kashghar, Yarkand, Khotan, Maralbashi, Kucha and Loulan has been disclosed by the results of expeditions sent out in the first decade of this century. Among the numerous documents was a considerable number written in Ancient Khotan, but in a dialect of the akas, or Indo-Scythians, who from the first century BC to the third century AD were dominant in North-western India. Volume I of Khotanese Texts was published in 1946, Volume II in 1954 and Volume III, which completed the publication of the longer texts in 1956. Volume IV containing the aka Texts from the Hedin Collection appeared in 1961. The fifth volume completed the printing of the texts. When it was published in 1963, it contained a large number of fragments and other pieces published for the first time, as well as the Hoernle Collection, the Samguata-Sutra folios and the Karma Text."
