Good books for a Northern Pagan? (Asatru, Odinism, etc)?

Good books for a Northern Pagan? (Asatru, Odinism, etc)?

The Eddas, The Nebulungalied, the Volsunga Saga.

Geeb's suggestion is accurate.
Do not buy any of the popular how to bull, stay away from the rune books, stay away from anything that cites sources from other pagan books.
Stick with Fact based books not religious opinion material. Go for scholarly works, and translations of the lore.
Oh and Jung's work may be popular among some heathens but it is by no means re constructionist.

Unfortunately we really don't have primary source information, that was written by ancient believers for ancient believers. So when diving through the Eddas and Sagas it's important to remember that almost all of it was written by Christian scribes a few centuries after conversion.

Source Lore: The Eddas and Sagas (Heimskringla, Gesta Danorum, the Ango-Saxon Chronicle, etc.), Skaldic Poetry, Tacitus' Germania, Beowulf and other Anglo Saxon sources like the Lacunga. Also the reports from traveling Arabic men like Ibn Fadlan.

Scholarly works about the ancient culture: Grimm's Teutonic Mythology (all 4 volumes), Fletcher's Barbarian Invasions, Dubois' Nordic Religion in the Viking Age, Simek's Dictionary of Northern Mythology, texts from Hilda R Ellis-Davidson and Turville-Petre are also great.

Modern religious texts by pagans for pagans - Gundarrson's Our Troth Volumes 1 & 2, Krasskova's Exploring the Northern Tradition

My advice is to stay FAR away from anything contemporary. We have plenty of information if people AR willing to look for it. Attempting to glean how to practice heathery in some sort of Asatru 101 book is just impossible. All you are doing is reading someone Else's UPG, usually really horrible ones at that, with out any sort of real base in the worldview of your own. Like Krasskova's Exploring the Northern Tradition for example...

It depends on what you are looking for out it.

Anything by: Diana Paxson, Edred Thorsson, Freya Aswynn, Kveldulf Gundarsson, or Thor Sheil. I've been influenced most by Thor Sheil and Diana Paxson. Uncle Thor's website is at:
