Kind and Benevolent Sir Google – I salute you!
Google has provided yet another wonderful resource for us: A font repository of beautiful fonts that are all free and legal to use because they are open source. Google Web Fonts make it easy to use these fonts on your website by generating the short line of code that you can copy and paste in the <head> section of your website to call the font for use in your style sheet. It calls the font using the Web Open Font Format so that it will render the correct font on all modern browsers.
