洪頤煊，字旌賢，號筠軒，浙江臨海人。與弟震煊，同以經學受知於阮元，元嘗謂：「台郡能讀書者，惟此二人。」（《定香亭筆談》，卷二）震煊識卓業精，好學勤勉，年四十而卒，著作僅《夏小正疏義》、《檆堂詩抄》傳世。頤煊淵深博雅，通達事理，於學無所不窺，著作亦甚豐，有《禮經宮室答問》、《孔子三朝記》、《諸史考異》、《漢志水道疏證》、《管子義證》、《讀書叢錄》、《台州札記》、《筠軒文鈔》、《倦舫書目》等二十餘種。其中《讀書叢錄》為頤煊五十歲後，學術精熟時所作，全書凡二十四卷，一千六百餘條，皆考經史百家之說，前八卷論經，九至十二卷論小學，十三至十六卷論諸子，十七至二十三卷論《史記》、《漢書》、《後漢書》，末卷論宋元版本，考證之精，包攬之廣，最能展現頤煊學術之菁華。故李慈銘《越縵堂讀書記》視此書為窮經之寶藏，足以與王念孫、引之父子之《經義述聞》、《讀書雜誌》，臧庸之《經義雜記》、梁玉繩之《瞥記》、《人表考》，陳壽祺之《五經異義疏證》比肩。洪頤煊著述繁富，本文以《讀書叢錄》為綱，參校頤煊友朋文集、詩集等相關資料，以及頤煊傳世之各種著述，詳細考察其撰作動機、全書體例與內容，或將有補於清代考據學史論述之一隅

Yi-Xuan Hong, who styled himself as Jing-Xian and Yun-Xuan, was born in Linhai, Zhejiang. Yuan Ruan once complimented him and his brother Zheng-Xuan Hong, ＂they are the only two scholars in Taizhou＂. Yi-Xuan Hong was a man of profound erudition and abundant literary works; he had published more than twenty types of books including ＂Questions and Answers for Rituals and the Palace＂ (＂Li Jing Gong Shi Da Wen＂) and ＂Confucius Records of Three Regimes＂ (＂Kong Zi San Chao Ji＂). Among all his works, Reading Series (＂Du Shu Cong Lu＂) was written when he reached mature wisdom after the age of 50. The book composed of 24 chapters and more than 1600 articles, carefully verified various expositions, comprised encompassing contents, and perfectly presents the essence of his academic accomplishments. As recorded in Tsi-Ming Li's ＂Yueman Hall Reading Diary＂ (＂Yue Man Tang Du Shu Ji＂), the book is considered a treasure which can be compared with ＂Interpretation of Classics＂ (＂Jing Yi Shu Wen＂) and ＂Reading Notes＂ (＂Du Shu Za Zhi＂) of Nian-Sun Wang and his son Yin-Zhi Wang, ＂Notes of Classics＂ (＂Jing Yi Za Ji＂) of Yong-Zhi Zhang, ＂Note of Glance＂ (＂Pie Ji＂) and Textual Research of Exemplars (Ren Biao Kao) of Yu-Sheng Liang, and ＂Comments on Different Interpretations of the Five Classics＂ (＂Wu Jing Yi Yi Shu Zheng＂) of Sho-Qi Chen. Among the abundant literary works of Yi-Xuan Hong, the study focuses on the ＂Reading Series＂ (＂Du Shu Cong Lu＂) and supports it with relevant data such as his writing and poetry anthologies and his remaining works, in order to carefully examine the writing motivation, style and editorial method of the ＂Reading Series＂ (＂Du Shu Cong Lu＂), expecting to contribute to the future textual researches of the Qing dynasty
