Abstract: Many summaries of Siku QuanShu had been published in 20th century,so the derivation process of the summaries is increasingly clear. There are some matters in the summaries of Yibiantiyi, Zhouyiyihaicuoyao, and Dayicuiyan. Combined with other summaries, we can see: there are some successive relations among the summaries of the same book, Ji Yun’s revision about the Siku QuanShu Zongmu is mostly embodied in the touch up of characters and the unity of style, but had little correction in author, version and content. The summaries’succession of the same book is often complicated rather than straight-line,some book’s summaries are presented as two systems.In addition,the summaries those were put in the front of the books of Siku QuanShu in Pavilion Wenyuange were often replaced and recopied, but there were relatively few such phenomena in the summaries of Siku QuanShu in Pavilion Wensuge and Pavilion Wenjinge,so these summaries hve more meaningful to investigate the derivation of the summaries.

Key words: Yibiantiyi;Zhouyiyihaicuoyao;Dayicuiyan;replaced and recopied
