The ordering of the Sarum Customary

There is significant overlap in content between all three forms of the Sarum Customary: the oldest known text of the Old Customary, the revised version of the Old Customary, and the New Customary. There are also important differences, not least in their organisation and ordering. The ordering of each of these forms of the Sarum Customary is outlined here, with an indication of factors that may have influenced their contents and presentation.
