We occasionally get asked for the Code of Federal Regulations. For those who are unfamiliar with this resource, the CFR is: “The codified version of the general and permanent rules and regulations published in the Federal Register by the executive departments and agencies of the U.S. federal government. The CFR is organized into 50 titles which represent various subject areas.” (Per Hein Online.)
Cost and frequency of updates prohibit us from keeping it in print, but there are several ways to access it online. The Government Printing Office keeps an up to date version at: ecfr.gov. The site has several search options: you can search by title, or search inside the current CFR.
Searching for older editions of the CFR or need to do research not enabled by the government’s official portal? Using one of the library computers you can access Hein Online, which has CFR documents dating back to its inception in 1938.
When you select “Code of Federal Regulations” on the main Hein Online page, you are taken to a publication specific page that allows searching by text and citation, as well as locating by year, title, part, and section.
The CFR collection in Hein is also able to be browsed by year, title, etc.. 
Again, Hein Online is available on any library computer. The next time you’re looking for CFR resources, stop by your local law library.
