CFR Sections Affected

There are several different ways that you can find CFR sections affected in HeinOnline. Please note that this only works for material from 2015 and forward.

CFR Locator Tools

When using the Title/Part/Section Quick Locator or the CFR Citation Locator from the CFR collection homepage to find CFR material, additional information will display in the search result(s) indicating where the cited section was affected in the Federal Register*. For example, select 2015, Title 5, Part 531:
