A great book to start learning Animation principles with is The Animator's Survival Kit by Richard Williams. You can find Aaron Blaise on Proko and YouTube, he's an excellent animation teacher, and has a bunch of free online resources on traditional and digital animation. Also check out Mike Mattesi's Force series, Mike teaches figure drawing from an animation standpoint and it's well worth checking out. If you're working traditionally with pencil and paper, a lightbox will be a great addition to your drawing desk to help you place your characters in the correct position from page to page, Huion makes a great inexpensive LED lighbox which I really like. As far as digital goes, an iPad and Procreate Dreams is an incredible resource to start animating with, Aaron Blaise did a great demo using Dreams. Hope this helps!
