Kaibao Canon

The Kaibao Canon, also known as the Shu edition, since it was printed in Sichuan, and sometimes known as the Northern Song canon was a woodblock printed collection of Buddhist texts produced in the Northern Song dynasty.
The Kaibao Canon was lost but formed the basis for other canons, notably the Tripitaka Koreana. We also know its contents, since it was based on the Kaiyuan Shijiao Lu, which is included in the Taishō Tripiṭaka.
It was the first printed edition of a Chinese Buddhist canon, and effectively closed the canon.
It was begun in 971 and completed in 983.
