In the course of my career I have had the opportunity to work with many different types of people - from animators, 3D artists and illustrators. From their suggestions, as well as my own searches, I have attempted to keep list of sites and books that I have found helpful. Above is a list I have started for reference and will be updating on a regular basis as I find more resources. I hope you find the links and literature helpful as well.
