The first two and final entries are later additions to the manuscript. A large part of the text (folios 1-81) appears to be based on manuscripts made not much earlier than Codex Scardensis itself. Tveggja postula saga Jóns og Jakobs, for example, is copied from AM 239 fol. which is only a few years older than Codex Scardensis. The texts later in the manuscript appear, on orthographic and stylistic evidence, to be based on older works. These stay closer to their Latin exemplars, whereas the younger texts add in extra material.
