The Dongnan jiwen 東南紀聞 "Records of hearsay from the Southeast" is an anonymous biji 筆記 "brush notes" style collection written in the late 13th century, as can be seen from the content of the book. The transmitted version is a copy of what has been quoted of this book in the Ming period encyclopdedia Yongle dadian 永樂大典. The 3 juan "scrolls" long text includes 84 stories about the history of the Southern Song dynasty 南宋 (1127-1279) that ruled over southeastern China, hence the title of the book.
The scholar Yu Jiaxi 余嘉錫 (Siku tiyao bianzheng 四庫提要辨證) is of the opinion that the Dongnan jiwen was noting else than a collection of stories recorded in books like Tingshi 桯史 or Duxing zazhi 獨醒雜誌, and not a new text. The Dongnan jiwen is to be found in the collectanea Siku quanshu 四庫全書, Mohai jinhu 墨海金壺 and Shoushange congshu 守山閣叢書.
