This article looks at the figure of Katok Rikdzin Tsewang Norbu (kaḥ thog rig 'dzin tshe dbang nor bu, 1698-1755) who in his writings displayed a concern for primary source material such as old Tibetan documents and inscriptions from the eighth and ninth centuries. Richardson frames Rikdzin Tsewang Norbu against that of other Tibetan historians who cited inscriptions such as Gö Lotsawa ('gos lo tsA ba) and Pawo Tsuklak Trengwa (dpa' bo gtsug lag 'phreng ba). The article ends with a sketch of Rikdzin Tsewang Norbu's eventful life. (Ben Deitle 2006-05-23)
