Federal Regulations

A regularly updated, unofficial editorial compilation of C.F.R. material and amendments published in the daily Federal Register. The main eCFR page indicates when each title was "Last Amended." Each individual Title page also lists the date when the Title "was last amended," as well as how "up to date" the Title is (that is, the current update status). The eCFR includes the following features: "Timeline," which allows one to compare changes to eCFR content across time, and "Compare Dates," which allows one to compare any two dates, with the options to "Show changes as red/green or purple/orange" and "Show strike-through for removed content."

Enter the C.F.R. citation in the search box at the top of the page and then click the drop-down "Go to this citation" option. Note the "Currency" information in the box on the right-hand side. Click the "General Info" icon if one is listed.
