The permanent record
8 parts of the Code with an amendment history
A CFR part is amended, never replaced, so this view accumulates where the calendar decays. 8 parts are amended by at least 5 final rules in the record. 0 of them are always amended in the same rule as a sibling and are recorded on that sibling's page rather than on a second page repeating one list. Parts cited less often appear on their agency and sector views.
