Researching web font stacks, and I used to have a good set of sites to look at for this, but that was years ago and I've long since forgotten them.

What are some resources/websites in use today for finding font stacks, or new fonts, or good fallbacks? I'd also like this research to include fallbacks/system fonts that I could rely on for themes I'm creating.

Many thanks for suggestions and boosting!
