I know very little about the Vikings and I was hoping this would be the perfect place to change it. My knowledge on the topic includes pretty much what they have in the show on the history channel and a small report I did on Regnar Lothbrok. I hope this isn't too vague and I do realize learning history from that show is the equivalent to learning about Spartans by watching the movie 300
There's lots of great things out there. I've written up a few lists of recommendations in the past, and a quick search of my previous comments turned up this one and this one. Admittedly, neither of these is really perfect for an initial introduction. Peter Sawyer's Oxford Illustrated History of the Vikings might be one of the easiest places to start, but Brink and Price's The Viking World is probably the very best introductory resource, although it's written more like an encyclopedia than a cover-to-cover read. Price's The Viking Way is one of the most interesting introductions to pre-Christian Norse religion, and you can even see him lecture on it for free. Graham-Campbell's Viking Art is also a pretty cool read, though it only has a passing review of Viking Age history at the very beginning. Let me know if I can help you find anything more specific. Happy reading!
