Abstract: In Hunan Normal University’s Library, there is a Qing Dynasty codex of Clouds-Watching Gathering, in which include a square and red stamp “Imperia Academy” in bilingual design and many notes, corrections and deleting marks in red or black Chinese ink. It was the original submission by Bao Shigong, a book collector from Zhejiang in Qianlong years, which has been identified as a portion of the rare original draft of The Si Ku Quan Shu, a grand imperia library collection. Later, it changed hands to Yuan Fangying, an editor of Imperia Academy in Daoguang years, thus survived from the incident of Boxer (1900). Because of not only the codex itself but also the valuable traces of the Imperial Librarians, it provides us with new material in Si Ku Quan Shu research.
