Abstract: Yang Shoujing's Records of Book Collecting in Japan is an extremely special and highly academic and seminal document in the history of ancient Chinese literature.This book holds significant value for the current hotspots in the study of Chinese classics abroad,the general catalog of Chinese ancient books overseas,and the Global Collection of Chinese Classics Project.However,due to various reasons,a considerable number of the collation results have not been fully utilized at present,and one of the reasons is that this book has not been deeply collated.The publication of this book was carried out in a state where it had not yet been finalized,resulting in some technical errors that were largely overlooked by the academic community after its publication,thus affecting its use.These errors can be divided into three categories:First,individual leaves are misplaced,and second,individual leaves are missing.Both cases are obscured by the continuity of leaf codes in the center of the leaf.Third,there are also cases where the splicing of double-line small text annotations is misaligned due to the addition of texts.Only by delving deeply into the original texts can these errors be dug out and corrected.Meanwhile,the investigation of such errors can also provide reference for the in-depth collation of other ancient books.At present,artificial intelligence is flourishing,bringing infinite possibilities to the collation of ancient books,but it will also promote “pseudo-collation” and even “pseudo-annotation”.Advocating in-depth and even research-based collation can not only reduce “pseudo- collation”,but also lay a solid rather than superficial foundation for the inheritance of excellent traditional Chinese culture.

Key words: Yang Shoujing, Records of Book Collecting in Japan, stringing pages, missing pages, line transpositions
