Below are resources I have used in the past, or have come across and found them to be possibly useful in the future:

WhatFontIs is a great resource if you are trying to identify a font in a logo/image.

Font Awesome

Font Awesome is a great way to incorporate icons into your site, especially since you can use them in your css as well. They come out with new icons all the time too!
