Find Historical CFR Sections on HeinOnline

You’d be surprised how often it comes up. You’re doing regulatory research, examining say an environmental impact, and the issue started back in the 1970s with a company polluting a river. You need to see the Code of Federal Regulations (CFR) sections as they were at the time of the original incident. You might be surprised to learn that neither Lexis or Westlaw go back far enough in their coverage of the CFR to answer your question.

That’s where HeinOnline comes in, with its coverage of the CFR all the way back to 1938, the year the publication started. You can easily navigate by year, title, part and section to quickly get to your regulation in 70s. HeinOnline has other key resources back to their inception, including the Federal Register, United State Code, and Ohio Revised Code.
