In an East Asian Canonical Texts list, some Daoist texts should be represented - in my view beyond Daodejing and Zhuangzi. But what should those be? Not a easy question to answer. Even with religious Daoist - the history from Han through Tang dynasty is very varied, and the feel of the tradition also is very different with the emergence of Nei Dan.
Of these 10 volumes I had Volume 3. Below are some potential candidates: (I exclude Daodejing, Zhuangzi, their commentaries, other sutras/ commentaries, pure philosophers, and also encyclopedia, geographical works)
《修真十书》(石泰辑) - may be some selections here
Another possible work is the verses written by some of the Quan Zhen Daoist, such as 《重陽全真集》.
