《隋书·经籍志》(下文简称《隋志》)确立了四部分类法,但并不成熟。就其“子部”而言,子部本身就存在天然的缺陷。此外它还存在图书数量统计的失误、类目分配不合理、归类混乱、违背既定著录原则等问题。 “Sui Shu · Ji Zhi Zhi” (hereinafter referred to as “Sui Zhi”) established four class method, but not mature. As far as its “sub-unit” is concerned, the sub-unit itself has its own natural defects. In addition, there are some problems such as the errors in the statistics of the number of books, the unreasonable distribution of categories, the confusion of classification and the violation of established principles of narration.
