If you want to discover even more methods libraries, there is a lovely website that is a library of methods library (yes, I know, that's pretty meta).

Three things I like about this Library of Methods library

1. It's pretty meta: It's great for super curious people who want to go even further.

2. It's dead simple but great: The website is super simple to use and really puts the focus on discovering the different libraries instead of pushing you to stay on their website.

3. It's a community project with curation: You'll find on the website the favourite methods libraries of different designers. This can be pretty helpful for those who are curious but still feel a bit overwhelmed by the amount of possibilities.
