The Håkon Håkonsson version is also known as the "Codex Resenianus", after the historian Peder Hansen Resen who gave the only surviving version to the University of Copenhagen (unfortunately later destroyed in the 1728 fire at the Copenhagen Library). In Norwegian it is found in the Norges gamle Love (I, 121–258) as "Den ældre Frostathings-Lov". A modern Nynorsk edition was published in 1994.
