Most if not all modern scholars have . . . given up any hope of reconstructing . . . an
original [Buddhist] canon by means of comparing the earliest surviving versions of the texts. . . the essential problem is that by the time of the earliest available testimonia, Buddhist tradition had already differentiated into several, perhaps many regional divisions with significantly diverging texts and doctrines, no one of which can legitimately be privileged as the “oldest” or “most authentic.”When one compares, for example, the Chinese versions of the major non-Mah?y?na s?tra collections . . .one finds . . a considerable degree of agreement between them and the corresponding Sanskrit and P?li collections, but also significant differences in the contents, arrangement and location of a great many of the s?tras. Depending on one’s preconceptions and point of view, one may emphasize the broad correspondences over vast ranges of time and space and understand them to show the overall unity of the Buddhist s?tra literature even to the point of assuming that they ultimately derive from a single archetypal collection; or, one can stress the extensive discrepancies in contents and arrangement and take this as an indication of the fundamental diversity of the different Buddhist traditions, suggesting that they cannot be traced to any unitary source [ie an original canon].

enables one to identify the Chinese, Tibetan, and Sanskrit ‘parallels’ or ‘counterparts’ to the suttas of the four main Pali Nikayas – or vice versa. It is designed for those whose interest in the Early Buddhist discourses extends beyond the limits of the Pali Sutta-pitaka to include the extensive corresponding materials found elsewhere: the Agamas and individual sutras preserved in Chinese, the occasional sutra translations contained in the Tibetan Kanjur, and the numerous published fragments of sutras in Sanskrit and related languages. As well as showing the correspondences as described above, Sutta Central allows one to access the texts directly in their original language (Pali, Chinese, etc.) and, where available, in modern language translation (e.g., English, French, German, Spanish).
Pretty amazing! At this point it looks like something only scholars will avail themselves of, but eventually the insights generated by this kind of work will inform the understanding of what the Buddha taught of students at all levels.
