I wanted to switch the look of a website by changing fonts, but I wanted to stick to fonts that are likely to be on most visitors computers. I looked around at websites for a good list of the candidate fonts. The best one I found is at ampsoft. It covers both Windows and Mac OS, shows regular and bold styles as well as screenshots with the top three web browsers, and seems fairly up to date. (If anybody knows anything to be wrong there, please post.) It solved my problem and some of you might find it useful too.
