The challenge of using fonts on the web is not a new one (we discussed it most recently after SXSWi). For years designers and developers have been using the same 15 fonts on the web, only able to implement non-web fonts with workarounds like Flash text, javascript and text in images. Now, that's beginning to change.

In May, Google announced the launch of the Google Fonts API, which allows developers to use a select number of web fonts in their pages. All the fonts in the Google Font Directory have open source licenses so they can be used on any website, from a private blog to a large commercial site.

You can check out the full list of fonts that are part of the Google Web Font API here: http://code.google.com/webfonts.
