Encyclopaedia of Daoism
As you can see entries are organised alphabetically (both English and Pinyin).
If you were looking for a text such as the Daodejing you could find it entered in both the “D” section and under “T” in the Texts entry.
If you were looking for Shangqing, for instance, it could obviously be found under “S” and also under “C” for Cults and under “H” for Highest Purity, and also under “M” for Maoshan Daoism.
