Do You Know Any Ancient Jewish Codices?

Dead Sea Scrolls, unfortunately, do not help my cause, because they are… scrolls. Nag Hammadi codices are also of no use to me for that particular project, because that’s mostly examples of early Christian and Gnostic literature.

Any help would be really appreciated. Links, names, locations – anything =)
