Version history of DOE O 457.1B

Every revision of DOE O 457.1B held in Directives, oldest first — 4 documents, with the supersession and cancellation dates that connect them.

This history is not a single line of descent. Some of these documents are here because one revision replaced several earlier documents at once, bringing their own histories with it.
