Collections, also known in English as Collectanea,congshu叢書 first appeared during the Song 宋 Dynasty (960-1276). These works are the result of compilations. Individual and State enterprises aimed at collecting transmitted books because they were linked to a specific topic, because they were rare and object of pride within a library, or to ensure transmission through history. Many of the books present in the Chi-Know-Po library were extracted from such Collections. This space is meant to allow access to the books with collections as a starting point.
