孫衣言（1815-1894）為晚清著名學者和古文辭家，畢生致力於鄉邦文獻之整理與研究，其藏書樓「玉海樓」為浙江四大藏書樓之一。著有《遜學齋集》，輯有《永嘉內外集》、《甌海軼聞》、《永嘉叢書》傳世。其《永嘉叢書》輯錄永嘉學派重要著作13 種，校勘精細，於文獻學上具有珍貴價值，此書的出現，掀起了溫州地區一場搜集整理鄉先哲遺著的文化運動，踵接其後的《永嘉詩人祠堂叢刻》、《敬鄉樓叢書》與之具有一脈相承的緊密關係。

Yiyan Sun (1815-1894), a noted scholar and ancient literature expert in the late Qing Dynasty, devoted his life to the sorting and study of local literature document. His depository of scriptures, Yuhai Pavilion, was one of the largest four in Zhejiang. He wrote Collection from Xunxue Cabinet (Xunxue Zhai Ji), and edited Collection of Native Sages and Foreign Scholars on Yongjia (Yongjia Neiwai Ji), Anecdotes from Ouhai Area (Ouhai Yiwen), and Yongjia Series (Yongjia Cong Ji). The appearance of Yongjia Series started a cultural movement on collecting, searching, and sorting lost works by native sages in the area of Wenjou. Meticulously proofread, Sun’s Yongjia Series that includes 13 major works from scholars of Yongjia schools is of priceless value in philology. His following Calligraphy Prints on Shrines for Yongjian Poets (Yongjia Shiren Citang Cong Ke) and Jingxiang Pavilion Series (Jingxiang Lou Cong Shu) both show a heritage of the spirit extremely close to that of Yongjia Series.
