Have you ever seen a font in print and wanted to use it, but couldn’t figure out what it was. Well there are 2 places you can go for identification. You can upload a .jpg to myfonts.com or you can answer a series of questions at identifont. Even though myfonts.com asks for you to keep space between the characters, I’ve used their system for script fonts, it gets pretty close and gives you multiple fonts to compare.
Overall a good tool to use. Not like the old days of thumbing through thousands of pages of fonts to compare serifs and weights.
