I have a deep interest in mythology and folklore, with extra love for the ones from Sweden and the Norse myths. I find it fascinating how vastly different some of the legends about the same being can be!
I’ve gathered a small collection of books related to the Scandinavian folklore and Norse mythology in my bookshelf. Most are written by Swedish authors, even if they cover a more general nordic area. A few have authors from outside of Sweden, but they are a minority. Most sources that aren't in Swedish are articles and essays on the subject.
A dream of mine is the compile these into a custom collection. Each of the beings mentioned in these sources would have their own document.
