Kaibao Canon
The Kaibao Canon (開寶藏), also known as the Shu edition (蜀版), since it was printed in Sichuan, and sometimes known as the Northern Song canon (北宋刊経) 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.
