Each section of the FCC rules has a regulatory history at the end
of the text in the form of a list of citations to the Federal
Register. In addition, rules not yet effective but published in
the Federal Register are typically printed at the beginning of
the text of a section. The table below sorts these citations by
date (volume and page number) with the most recent first along with
the month and year of publication and the cited rule section
along with the title of the rule part and the title of the rule
section. Consulting
this table, it is easy to see recent rule changes of interest.
