Rare Texts From Tibet : Seven Sources for the Ecclesiastic History of Medieval Tibet [Introduction in English and the Rest of the Book is in Tibetan Language]

From the Introduction: "The texts presented here have been reproduced as found in the printed sources available, largely retaining all the orthographical peculiarities, although these occasionally display some faulty and defective renditions. The punctuation chosen in the present book generally follows the original texts too, both what concerns the division and lay-out of the texts into chapters but also into paragraphs, still a modicum of liberty has been taken by the editor and some slight reshufflings have been made. Although due heed has been paid to the rules of the indigenous punctuation, the final arrangement has been conducted to the discretion of the present compiler, out of a preliminary contextual reading of the texts. These paragraphs could have been arranged differently and the choices made might to some occasionally appear somewhat arbitrary. Another arrangement, especially a different chapter division surely would be equally representative and feasible. 

As may be gauged from the \'Bri-gung set listed in the adjoined appendix, the compilers did not follow any strict editorial principle -- occasionally parts of the same author\'s bka\' \'bum are allocated to different sections in the collection. ........"
