Another good resource that has helped me was www.spellsandmagic.com it is better for high magic such as summoning, advanced circle casting, scrying, astral projection, etc. I hope these sites can help you.

Another note, I started my research at http://spellsandmagic.com and a lot of the excercises help build up your psychic powers, and the stronger your psychic powers are then the better most spells and rituals are goning to work for you. If you start out with the spells and rituals, they probably aren't gongi to work as well without any kind of knowledge or experience using your psychic abilities. A lot of people who don't have the knowledge of how to use them wil ltry spells first, and when the spells dont work for them they just give up the craft, so i would highly suggest building up your psychic abilities first. Have fun!
