For the longest time I've used 1000freefonts.com as a resource when I'm looking for a font to meet a specific style of a new site. As of today however, it looks like it's time to move on!
Urban Fonts has over 8000 fonts (and dingbats)! That's just simply unbelievable. Having looked through the site, it looks to be designed very nicely; and quite easy to navigate. They offer custom text previews, custom colors and quick mouseover previews.
