Not always about type.

If you know of a list containing all/most of the good* foundries/vendors supplying webfonts I’d like to see it. Until then here is mine. I’ll be adding and updating as I find them.

Vendors

1. fonts.com (multiple foundries)
2. Font Deck (multiple foundries)
3. Fonts Live (multiple foundries)
4. fontspring (multiple foundries)
5. Font Squirrel (multiple foundries, all free)†
6. Typekit (multiple foundries)
7. WebINK (multiple foundries)
8. Webtype (Ascender, Font Bureau, Microsoft, Monotype)

Foundries

1. FontFont (Select fonts from their library)
2. Typonine
3. Typotheque

* Subjectively speaking, of course. 
† Unless the foundry from which you’ve licensed the type allows modifications I would not use their @font-face generator. 

EDIT: I started this list and then was reminded about Webfonts.info by my pal, Stephen Coles. So now we can all just use that and harass them if something is missing over there. :)
