Reddit reviews Iceland: Second Edition (Classic Geology in Europe)

A lot of the info in the album was stuff that I took note of while at the actual location; there was usually a sign that gave at least some information in English. If I wanted to know more I looked it up later. I did read these ahead of time though:

• Iceland: Land of Sagas - nonfiction - good primer to get a basic overview of the country with some really nice details here and there (some of the notes I took while reading made it into my plans later)
  
• Iceland: Second Edition (Classic Geology in Europe) - nonfiction - mostly used as a reference for really detailed geological stuff
  
• Njal's Saga - one of Iceland's sagas, you'll see sagas referenced an awful lot so I liked having a vague idea of how that is like
  
• Independent People - I didn't finish this by the time I went to Iceland, but it is a good story and perspective on the culture

I bought this book after a vacation to Iceland and found it to be very informative. It's well written and has good maps. I think it could be a good starting point for you.
