1.9

右別錄之中曲分為七。一有譯有本。二有譯無本。三支派別行。四刪略繁重。五拾遺補闕。六疑惑再詳。七偽邪亂正。就七門中二乘區別三藏殊科。具悉委由兼明部偶。

The Classified Catalogue above is subdivided into seven [sections]: first, texts with translators and extant texts; second, texts with translators but no extant text; third, independent circulation of extracted sections; fourth, paring redundancies and duplicates; fifth, gathering omissions and supplementing deficiencies; sixth, re-examining doubtful texts; seventh, spurious and heterodox texts corrupting the correct. Within these seven sections, the two vehicles are differentiated and the tripiṭaka is treated in distinct categories, detailing origins and reasons, as well as clarifying matches of works.
