The fine folks at The League of Moveable Type: A Collection of Open Source Fonts are “done with the tired old fontstacks of yesteryear. Enough with the limitations of the web, we won’t have it. It’s time to raise our standards. Here, you’ll find only the most well-made, free & open-source, @font-face ready fonts.” While there aren’t tons of options yet, what is there is quite good. Check out, for example, the Sorts Mill Goudy above. If you are a typeface designer interested in making your high-quality work available under the Open Font License, think about joining the League of Moveable Type.
