《四库全书》中所收大典本宋人别集，在四库馆稿本、阁本、武英殿聚珍本、传抄本等“中间本”及提要等方面，遗存了卷数变动的痕迹。这些异变由据御旨删去青词等体、为与提要所言卷数一致而删去某些卷次、相同内容重编等诸多因素所致。卷数异变揭示了早期版本有独特价值、七阁本所据并非全为同一底本等规律，也部分修正了学人对四库馆臣辑佚工作的负面评 价。

Anthologies of Song Dynasty collected in Siku Quanshu marked some changes in volume class numbers of some intermediate copies, such as the manuscript of Siku Academy, Ge edition, Wuyingdian edition, transcripts and synopsis, etc. These deviations were caused by several reasons. Some volumes were cut off according to the imperial edict or to be in accordance with the synopsis, and some were deleted as the same contents were reedited. The deviations of volumes reveal the extraordinary value of the early versions. It also exposes that seven kinds of Ge edition aren’t entirely based on the same original edition. Besides, the paper partly adjusts scholars’ negative opinions on the collecting work of Siku Academy.
