Norse Revival:Transformations of Germanic Neopaganism, a new book by Stefanie von Schnurbein (Humboldt University, Berlin) appears to be available as a free download from Brill. (Yes, I am using the words free and Brill in the same sentence.)
Norse Revival examines international Germanic Neopaganism (Asatru). It investigates its origins in German ultra-nationalist movements around 1900, its attempt to gain respectability since the 1970s and its intersections with historical and current debates on race, religion, gender, and aesthetics.
