For Hakkilyupeon(學記類編) classifying and editing Nammyeong(南冥) Jo Sik(曺植)'s reading note, it needs to research and identify the source of quotations come from Hakkilyupeon(學記類編) instead of recomposing Nammyeong Jo Sik's studies through Hakkilyupeon(學記類編). Therefore, the purpose of this paper was to identify the structure of Hakkilyupeon(學記類編) 1st volume. The results of this study were as follows. Hakkilyupeon(學記類編) 1st volume was roughly divided into '太極天地·鬼神·性命·氣質性·心·通論', but as a result of analyzing the contents it was subdivided into '太極·天地·鬼神·誠·性命·心性情·仁·氣質之性·心·知覺·道心人心·天理人欲·情·志·意·道·德·忠恕·忠信·雜記'. This means that Hakkilyupeon(學記類編) was edited based on the cataloging of Jinsilu(近思錄), but 87% of quotations were actually grounded on the list of Xingli daquan(性理大全). Concerning quotations were not found from Xingli daquan(性理大全), could find them from Sishu daquan(四書大全) and 眞德秀's '讀書記', therefore supposed Xingli daquan(四書大全), Sishu daquan(性理大全) and '讀書記' as Nammyeong Jo Sik's scientific source. In addition, there were parts could guess that Nammyeoung Jo Sik read Zhuzi yulei(朱子語類), '河南程氏粹書', '河南程氏粹言', '木鍾集', '魯齊遺書', '居業錄' and so on. The structure of Hakkilyupeon(學記類編), which continues from 2nd volume to 5th volume, will be analyzed in the future studies.
