Although many versions of the texts of the early Buddhist schools exist, the only complete collection of texts to survive in a Middle Indo-Aryan language is the "Tipiṭaka" (triple basket) of the Theravada school. The other (parts of) extant versions of the Tripitakas of early schools include the Chinese Āgamas, which includes collections by the Sarvastivada and the Dharmaguptaka. The Chinese Buddhist canon contains a complete collection of early sutras in Chinese translation, their content is very similar to the Pali, differing in detail but not in the core doctrinal content. The Tibetan canon contains some of these early texts as well, but not as complete collections. The earliest known Buddhist manuscripts containing early Buddhist texts are the Gandharan Buddhist Texts, dated to the 1st century BCE and constitute the Buddhist textual tradition of Gandharan Buddhism which was an important link between Indian and East Asian Buddhism. Parts of what is likely to be the canon of the Dharmaguptaka can be found among these Gandharan Buddhist Texts.
