Looking To Start Learning Shamanism, Where to start? Options

I just recently became very interested in Shamanism
I don't really know anything about it, but I'd like to be more connected with nature. I also would like to learn Astral Projection which I have been trying to learn for a couple months now, and from the little bit I've read it seems there's a lot of OBE stuff going on with Shamanism

I was wondering what are a couple good books to start me off?
I've only read a little bit of Shaman, Healer, Sage by Alberto Villoldo

I'm new to shamanism as well, it opened itself to me about a half a year ago and I've been kind of fumbling around. The best thing I've found is to listen to your spirit guide (mine's been with me for a long time, if you can't hear/see your guide you may want to consider locating/opening up to yours or finding an astral teacher) and traveling to the upper world, where many teachers reside. First hand experience kind of tends to be the best teacher, so travel through some of the planes (middle and upper world tend to be good for starting journeys I've found.) and just get to know the land, listen to it. Sometimes you may run into trouble, but your body is only a thought a way as long as you don't cut off totally (which I've never really encountered personally but I've heard that it can happen) from your body. If you have someone in your area that is knowledgeable, talk to them if you feel comfortable. Also, books can be helpful references. I've read "In the Shadow of the Shaman" by Amber Wolfe and "The Shamanic Witch" by Gail Wood. They can be repetitive but they both offer some good insights and tips and as all books on the esoteric should be, they are good references. Probably the most helpful thing I've learned, is to let change flow. Shamanism, for me at least I can't speak from anyone else, is firmly founded in change. Changing from one state to another, from physical to spiritual, from sick to well, from man to animal (while shapeshifting if thats one of your paths). I hope something from this was helpful, from one shamanic freshman to another =]

Would a spirit guide be the same as an animal totem?
I'm gonna try finding a teacher in the astral whenever I can learn astral projection.

Thanks for the info everyone
