 Only the first edition has been the basis for all following editions (through two Qianlong era editions).Analysis shows that the composition of "Guwen Guanzhi" is heavily based on a former anthology produced by an altogether different compiler.Though the "blueprint" has often been presumed to be the "imperial" anthology "Guwen yuanjian" (古文淵鑑), edited during early Qing dynasty under the personal supervision of the Kangxi Emperor, and including the standard commentaries required for the imperial examinations, this has proven not to be the case.
