「題跋」一詞聯用，多見於北宋中葉之後的文獻，如米芾《寶章待訪錄》以及沈括《夢溪筆談》等，本指畫帖上之題寫內容。而作家文集、文學總集中，《歐陽文忠公全集》於文章分類設有「雜題跋」類，呂祖謙《宋文鑑》則始設「題跋」類；而後明吳訥《文章辨體》、徐師曾《文體明辨》中為「題跋」所作的界定，皆針對書籍篇文而言。現今「題跋」一詞的界定眾說紛紜，尚無定說，本文擬分析畫帖題跋與書文題跋的發展脈絡，期提供畫帖題跋與書文題跋較為合理之界定。

”tyi bar” was used in mifwu's (米芾) ”bao chang dai fang luh” (寶章待訪錄)and shen kuo's (沈括) ”meng chi pi tan” (夢溪筆談). It meaned the postscript of painting and calligraphy. ”ou yang wen chung kung chuan chi” (歐陽文忠公全集) established ”tsa tyi bar lei” (雜題跋類). ”sung wen chien” (宋文鑑) established ”tyi bar lei” (題跋類). ”wen chang pien ti” (文章辨體) and ”wen ti ming pien” (文體明辨) defined for ”tyi bar” (題跋). They meaned the postscript of book and writing. Now the definition of ”tyi bar” (題跋) is not sure. My thesis offered a reasonable definition by studying the development of the art's postscript and the book's postscript.
