What are good encyclopedic books about mythical creatures?

Hello folks, I recently wanted to expand my knowledge on mythical creatures to use in writing stories. I seem to gravitate to the more common creatures like fairies, oni, giants, angels, tengu etc.

I think it might be because of a lack of knowledge, which is why I would like some sort of encyclopedia about mythical creatures.

So far I'm interested in:

Michael Dylan Dylan Foster
Pandemonium and Parade: Japanese Monsters and the Culture of Yokai

Katharine Briggs
The Fairies in Tradition and Literature (Routledge Classics)

M. Belanger
The Dictionary of Demons: Names of the Damned

Any other suggestion about either better or more extensive resources on those topics, or about other cultures like german, korean etc would be appreciated
