A lot of what I know about character animation (and 3D graphics in general), I learned through the efforts of many wonderful people who were willing to put forth the effort to share what they know with the rest of the 3D community on the Internet. Thank you very much to everyone who makes this free learning available to everyone! Here are some of the sites that I've found most useful in my quest for knowledge:
