本文以喬哀思的手稿為例說明頁緣空間的功能，包含了擴張、過渡、連結與同化。喬哀思手稿的邊緣明顯地展現了其書寫的延伸力。他在寫作時已盡量靠頁面右邊書寫，在左側留下大量空白，但這些空間經常不足以容納新的素材。為了增添更多邊緣空間，喬哀思大多數時候只在右方頁書寫，保留左方頁作為增補與修訂使用，它因而成了左側邊緣的巨大延伸。此外，對文本而言，邊緣空間是一種過渡時期，讓文本能夠面對它自身的未來。邊緣的連結功能還將串織文本的不同部份。同化的功能則顯示喬哀思的手稿邊緣存在著其他文本衍生的素材，同時，喬哀思的文本也寫在其他文本的邊緣。

This paper analyses the functions of the margin of James Joyce’s manuscripts, which include expansion, transition, connexion and assimilation. The expansive force of Joyce’s writing is openly displayed in the margin of his manuscripts. Although he made sure to start writing well to the right of the sheet, leaving a copious left margin, this space often proves to be too small to accommodate all the new material. Therefore, most of the time, he wrote only on the recto of folios, reserving the verso for additions and corrections, turning it in effect into a vast extension of the left margin. Moreover, I argue that the text, in transit, is faced with its own future in the margin. Besides, the margin functions to weave connections between different parts of the text. Finally, from the aspect of assimilation, we will see that the presence of other books, other parts of the same text, and other versions of itself in the marginal space of Joyce’s manuscripts.
