A fantastic book called simply Nordic Larp, edited by Jaakko Stenros and Markus Montola. It was published in 2010 and was fiendishly hard to get a hold of –– until they put it online for free as a pdf about six months ago. http://tampub.uta.fi/handle/10024/95123
“This document ended up being the draft for what is now The Foundation Stone of Nordic Larp, one of the two 2014 Knutpunkt books, and a much better version of this document that includes almost (although not quite, due to length reasons) everything here, plus some additional stuff comissioned specifically for the book. Feel free to read on, of course, but I really do recommend the book instead.”
