The above links will give you a general feel for the beliefs of many Heathens and help you orient yourself some.

I personally recommend Gods and Myths of Northern Europe for a general overview of many Germanic gods. But, one must keep in mind that the book is over 40 years old, and some of her scholarship has been shown to be off the mark in some areas. Even so, it's an enjoyable read and confers some knowledge.

Another book I particularly like is the Norse Myths; while Crossley-Holland takes some liberty in adding details and dialogue to the myths, it's a fun read that gives you a feel for the surviving mythological stories.

Now for some resources on magical practices - of a scholarly nature, save the how-to's and the manuals of magic[k] until you actually know some facts about what we really know of Germanic heathen magic.

An essay on healing hands and magical incantations in Eddic poetry: http://sydney.edu.au/arts/medieval/s...6-nasstrom.pdf

An essay on the idea of witches gathering and the transvection of the Middle Ages and whether it has roots in pre-Christian belief: http://userpage.fu-berlin.de/~alvismal/7sabbat.pdf

An essay upon magic represented in the Sagaic literature: http://sydney.edu.au/arts/medieval/s...5-mitchell.pdf

Finally a good piece on seiðr: http://www.vikinganswerlady.com/seidhr.shtml (this site in general has lots of good reading from a historical perspective)

One thing to keep in mind is to never believe any second-hand source without further study. One sad fact about many pagan religions is that they tend to be misrepresented or based on bad facts when it comes to modern, non-scholarly publications. I'd advise you of staying clear of any "Asatru 101" or "Viking Magick!" books. At least for now. They tend to be not worth the paper they're printed on.

A final note is to remember that the surviving Eddic poetry and sagaic literature that mention gods or religious practices are nearly all written anywhere from 150 to 250 years after the conversions. Thus, they can never be taken at face value, or seen as purely word for word accounts of genuine Germanic myths or rituals. So, when reading the Eddas and Sagas, keep that in mind.

*deep breath* this is probably an overload for you. But hopefully you find some information that furthers your understanding of Germanic Heathenry.

Good luck
