Modern Buddhological studies have been enhanced in recent years by the fruitful researches of the many scholars who have focused their attention on the primary literature of Buddhism. To be sure, one of the most promising endeavors in understanding the historical, religious, philosophical, and social dimensions of Buddhism has been the textual approach in which "the texts are allowed to speak for themselves." Nevertheless, with so many differing aspects to examine, in the various Buddhist countries and languages, the organization of this overwhelming corpus of literature has proved to be the researcher's dilemma and the bibliographer's nightmare. Of course we have several specific collections of catalogues such as A Complete Catalogue of the Tibetan Buddhist Canon edited by Hakuju Ui, Munetada Suzuki, Yensho Kanakura, and Tokan Tada, and Habagirin Fascicule Annexe (Tables du Taisha Issaikyd), edited primarily by Sylvain L~vi, Junjiro Takakusu, and Paul Demi~ville.
