五代時期所編纂的《舊唐書》有〈文苑傳〉一卷，共分上、中、下三篇，傳前有史序一篇，傳末有史贊一則，並載錄104位傳主生平資料。 透過史序，不難發現史家對於高度仰賴典範作品(諸如《詩經》、《楚辭》)，而發展出來「是古非今」的批評論述，帶有負面的評價。其嘗試通過南朝沈約的新變思想，正視、肯定每一時代文學嬗變的現象，並欲藉此回歸三代「經邦緯俗」的文學期待。而這些思想，也具體展現在史贊所謂「國之華采，人文化成」一語之中。 在傳文裏，就所徵引的文學作品看來，有兩項重要現象與結論：第一、重視討論公共事務的作品，此即呼應強調文學社會性的意義。第二、重視藻飾的語詞、駢偶的句子、新體（或謂相對於古體的「今體」）詩文，此乃重視文學「新變」的具體表現。此外，史家透過元稹肯定杜甫，透過張說肯定四傑（尤其楊烱）與開元時期重要文士，同時更建構了張說為開元領袖，元、白是元和主盟的文學史圖像。因此，縱然傳文多屬描述語言，可是通過徵引作品與重要作家的言說，都可以發現史家肯定唐朝新變的文學表現。相對於此，古文家韓愈、李翱等人的「務反近體」，就不易獲得史家的青睞了。

Jin Tang Shu Book was compiled during Five-dynasty period of Chinese history and there is a Literator Biology which included three piece, There are one piece of preface and one piece of afterpiece. It recorded 104 literators in total. By the preface, we can find the historians developed a disadvantageous description and conception that “commend ancient dynasties but negative now” by believing faithfully some paradigm litertaures (like Shr-Jing(詩經)、Chu-Tse(楚辭)). They tried to understand Shen-Yue (沈約)'s innovative conception of literature then face and approve this phenomenon which change of literature in every dynasty, and they went to get the literature expectation of administrating policy in San-dynasty (三代) period. In the Literator Biology, we can get two of important phenomenon and conclusions by observing the literature quoted by historians. First, historians approved the sorts of literature that discussed civil events, and this is corresponded with their emphasis with the social function of literature. Second, they maximized the beautiful vocabularies and antithetic sentences, new style poem. This is the embodiment of maximizing innovation of literature. Historians also approved Du-Fu (杜甫) by Yuan-Jen (元稹), approved Sz-Jie (四傑) whom be the most important literators in Yuan-Jia (元嘉) period by Jian-Yue (張說), and historians even constructed the historical imagine that Jian-Yue (張說) was the captain of Kai-Yuan (開元) literal circles and Yuan (元), Bai (白) were the captains Yuan-He (元和) literal circles. Hence, although the Literator Biology was wrote with describable language, we still can find the face that historians approved the innovative performance of Tang-dynasty literature by what literature and literator's opinions historians have quoted. Relatively Han-Yu (韓愈)、Lee-Au (李翱) were overshadowed, because of their opinion that back to the old stylish literature.
