《不是文字》收錄香港作家西西的四十五首英譯詩作，中英雙語，是 Hong Kong Atlas 香港文學英譯系列中的其一出版書籍，為首批以文學翻譯在國際文化地圖上記下香港足跡的著作。
Xi Xi (also known as Sai Sai), pseudonym of Cheung Yin, is one of Hong Kong's most beloved and acclaimed writers, as well as a stylistic innovator across genres. She has published two poetry volumes, seven novels, twenty-one short story and essay collections, and one stand-alone novella, and many of her books have been reprinted in Taiwan, Hong Kong, and Mainland China.
Her attitude toward literature, and life in general, perhaps is best epitomized through her chosen pen-name. For Xi Xi, the graphic quality of the Chinese character xi 西 looks like a girl in a skirt playing a game similar to hopscotch. Duplicating the characters side-by-side calls to mind the frame of a film, with the girl hopping from one square to another.
Not Written Words is one of the first publications in the Hong Kong Atlas series. Hong Kong Atlas is an important first step in expanding the English-language canon with a range of Hong Kong voices. By drawing on literature, translation and creative culture as a way of remapping a global city, the Atlas project offers alternative histories to Hong Kong through its own literature.
