The description of Icelandic institutions is mostly based on an old article of mine, which provides considerably more detail. For more information on saga period Iceland, by a more expert author, see the books of Jesse Byock (Jesse L. Byock, Feud in the Icelandic Saga (University of California Press: 1993), Medieval Iceland : Society, Sagas, and Power (University of California Press: 1990) ). William Miller has also written on the subject, from a legal perspective very different from mine (Bloodtaking and Peacemaking: Feud, Law, and Society in Saga Iceland, (University of Chicago Press: Chicago: 1990).)
