The study of Tang Dynasty poetry collections serves as a third path beyond focusing solely on writers and their works. In ancient times, attention was paid not only to distinguishing styles and examining reflections but also to the practical experience of compiling collections and the concerns of writing. With the publication of facsimiles of ancient manuscripts from Dunhuang and Japan, combined with the recent reevaluation of studies concerning poetry collections, the source and compilation principles of poetry collections, particularly from the Tang Dynasty, have attracted increasing attention from scholars.This book centers around Tang Dynasty poetry collections and examines issues such as the study of poetry collections, prefaces and concurrent entries, documentation, order of volumes, and the influence of Confucian Classics and History and Philosophy sections on the compilation of Tang Dynasty poetry collections. It also discusses the practice of concealing names in family collections, the exemplary editing of the poetry collections of LI Bai, DU Fu, YUAN Zhen and BAI Juyi, textual forms and common practices related to poetic themes, among other topics. By discerning the compilation principles of Tang Dynasty poetry collections, this study not only serves as a reference for the compilation of poetry collections throughout history but also plays a role in observing trends and seeking sources in the field of medieval literature restoration.
