《説郛》所收王易《燕北録》,向來因其中珍貴的契丹史料而爲史家所重,但此書名實不符的問題却一直無人問津。首先,作者王易出使契丹的時間與書中記載的時間有着不可彌合的矛盾;其次,該書與武珪《燕北雜録》在内容上存在雷同。全面對比兩書不難發現,《説郛》本所謂《燕北録》的内容很可能全盤出自武珪《燕北雜録》,而與王易之書無涉,其改題今名則應是文獻流傳過程中“張冠李戴”的結果。 “The Book of Songs” The Book of Records of YanBei collected by the Book of Songs was always valued by the historians for its valuable historical materials of Khitan. However, the issue of the book’s true name has been ignored by all. First of all, the author Wang Yi’s time to engage Khitan has an irreconcilable contradiction with the time recorded in the book. Secondly, the book is similar in content to that of Wuyi’s Yanbian Zaolu. Comprehensive comparison of the two books is not difficult to find, “said 郛,” the so-called “Yan North recorded” is likely to come from the contents of the martial law “Yanbian miscellaneous records,” and the book is not related to Wang Yi, Process “Zhang Guan Li Dai ” result.
