A. CFR Parts Affected from the Federal Register

Published by the Office of the Federal Register, National Archives and Records Administration (NARA), the Federal Register is the official daily publication for rules, proposed rules, and notices of Federal agencies and organizations, as well as executive orders and other presidential documents. The Federal Register contains rules and regulations which are regulatory documents having general applicability and legal effect. Most rules are codified in the Code of Federal Regulations (CFR).

Users are able to browse CFR Parts Affected from the Federal Register to find final and proposed rules that affect the CFR and have been published in the Federal Register within the past 24 hours, week, month, or within a specific date range.
