類書對應查詢系統目前提供對應查詢的類書有以下兩部：《藝文類聚》與《太平御覽》。《藝文類聚》成書於唐代統治的第7年（624年），為唐初弘文館學士歐陽詢等主修，內容總計約100萬字；《太平御覽》成書於宋王朝建立之後第25年（984年），由宋初翰林學士李昉等主修，總計約400萬字。由於這兩部類書均為新王朝建立之初、集國家之力延攬人力物力編修完成的，規模龐大，體制完整，成為我們觀察類書及其背後知識世界的最佳文本。本系統之目的在於提供一個對比觀察與分析的數位環境，讓有志於類書的研究者能對中國古代類書的結構與內容、及其所反映的知識分類和思想轉變有更進一步的探索與了解。

This system currently presents the “Yiwen Leiju Collection” and the “Taipin Yulan Collection.”Yiwen Leiju, completed in 624 A.D. with Ouyang Xun as lead editor, consists of roughly 1 million words. Taipin Yulan, completed at the hands of lead editor Li Fang in 984 A.D., 25 years after the establishment of the Song Dynasty, is comprised of over 4,000,000 words. Yiwen Leiju and Taipin Yulan are both massive in volume though different in scale. However, both were commissioned by the imperial court at the beginning of the respective regimes and compiled thorough in completion, so they would provide the best examples for understanding Leishu as a genre and the information they contain.

The purpose of the system is to provide researchers who are interested in traditional Leishu to compare and analyze the structure and content of the database’s collections. Furthermore, the system also offers a chance for more in-depth observation on the knowledge classifications and their reflective ideology changes in each Leishu.

This database provides classification browsing and corresponding inquiry.
