    This nearly bilingual chronology of Tibetan history is full of useful reference material, much of which has no doubt now been included in the dictionary listed above, but grouped here topically and in easy to use charts and lists. Lists in chart form the incarnations of the Dalai, Panchen and Jamyang Zhepa Lamas (including their birthplaces), as well as the lineages of the Sa skya (including its various bla brang and the lam 'dras tradition), the various lineages of the Bka brgyud schools (including the Black and Red Hat incarnations, the Stag lung abbots, the Dga' ldan abbots, etc. Lists of special importance to political history include the Yuan emperors' Ti shri (imperial preceptors) and Sa skya dbon chen, the various sde srid of the Dalai Lamas (1642-1952), a list of the actual rulers of Tibet from (1642-1951) pp. 82-86, a list and description of the Lhasa administartive offices of power (from the Dalai Lama to Finance Office and so forth) pp. 87-93. Also includes useful bilingual charts dealing with administrative divisions of Tibet (giving old and new names in Chinese and Tibetan).
