my Fontbook is a FREE and easy way to browse your font collection.  There is no software to download or install, everything is web based in an “iTunes” like window.

The font viewer allows you to easily review and catalog all of your installed fonts. Compare all of your installed fonts with an easy to use font viewer. Both list and swatch views help you quickly browse your font catalog. Organize your fontbook using tags. Tag fonts to describe a font style or tag fonts by project. You may rate fonts that you often use with the familiar star interface.  The gylphs view allows you to quickly scan characters and symbols. Looking for a specific dollar sign for a design? The font viewer makes it easy to find the right typeface.  The font metrics view displays guides to show default kerning, text baseline, and median height.
