X = Proceedings of Congress.
Y = Miscellaneous publications of Congress.
Z = Papers of Revolutionary period and first 14 Congresses.

the bureau may not have issued any publications belonging there. "General publications"

volumed in any series.
Beginning with figure 5 after the point, the various series are arranged alphabetically
as far as possible, and are assigned numbers. New series are added at the end
of the list. They take the next unused number.
