《讀呂子筆記補訂》一書，道光年間吳昂駒著，載錄於嚴靈峯《周秦漢 魏諸子知見書目》，其手稿本藏於中研院傅斯年圖書館，前人鮮有留意。過 去注釋《呂氏春秋》者未嘗參用此書，近年《子海珍本編》（2013年）與《傅 斯年圖書館藏未刊稿鈔本．子部》（2016年）始有影印出版，學界於茲得見 吳氏對《呂氏春秋》之研究成果。吳氏一書，乃據查慎行《得樹樓雜鈔》卷 五《〈禮記．月令》與《呂氏春秋》互異〉一文及其餘各卷筆記，以校訂《呂 氏春秋》。查慎行未及見畢沅校本（1789年），吳氏《補訂》則據查慎行筆 記並引畢沅、盧文弨、梁玉繩等人之校語，以補足查慎行之論說。本文從兩 方面討論吳氏《補訂》：第一，比較吳昂駒《讀呂子筆記補訂》與《適圜叢 書》本《得樹樓雜鈔》，以見吳本於版本學上之意義。第二，歸納吳氏校釋 《呂氏春秋》之特點，以補足清代《呂氏春秋》著述之研究。

"Revision Notes on Luzi" (Du Lu Zi Bi Ji Bu Ding) , written by Wu Ang Ju during the DaoGuang era of the Qing Dynasty, is recorded in Yan Ling Feng "ZhouQinHanWei Zhu zi zhi jian shu mu". The manuscript version is now kept in the FuSiNian Library which has not gained much attention by researchers who study Lushichunqiu. In recent years, "Zihaizhenbenbian" (2013) and "FuSiNian Tushuguan Cang WeiKan Gaochaoben * Zibu" (2016) were published, and this provides an opportunity for us to read the Wu’ s research findings. This book investigates Lushichunqiu based on ChaShenXing5s study on the textual variants between Liji and Lushichunqiu and his other relevant notes, which have been kept in "De Shu Lou Za Chao". Wu Ang Ju cited the commentary of Bi Yuan (1789), including Lu Wen Chao and Liang Yu Sheng, to support the study of Cha Shen Xing. This article will first compare both "Du Lu Zi Bi Ji Bu Ding" and "De Shu Lou Za Chao" so as to reveal the bibliological value of Wu’s book. Second, analyze the features of Wu’s writing in order to supplement the study of Lushichunqiu in the Qing Dynasty.
