The Taoist scriptural canon traditionally called the “Treasury of Tao” is the Daozang.
Daozang literally means “Taoist Canon” or “Treasury of the Dao.” It is not one single ancient book but a large collection of scriptures, ritual manuals, commentaries, liturgies, biographies, meditation writings, and technical works from multiple Taoist traditions.
The canon developed through repeated cataloguing and compilation under different Chinese dynasties. Collections were often reorganized, lost, or expanded, so the contents of one historical Daozang were not always identical to those of another. The Ming dynasty canon, printed in the fifteenth century, is especially important for modern study.
The Daozang should not be confused with the Tao Te Ching or the Zhuangzi. Those are major individual works associated with philosophical Taoism, whereas the Daozang represents the broader textual heritage of organized Taoist religion, including ritual and institutional traditions.
