Federal regulations change frequently, and keeping up can quickly become a nightmare, as tens of thousands of changes are made every year.

A new feature in Westlaw EdgeRegulations Compare — lets users see the most recent changes to a federal regulation and compare any two versions going back to 2005, saving significant time. Additions to a regulation are indicated by highlighting, while deletions are indicated by red strikethrough. This eliminates the painful task of manually comparing historical versions of the Federal Register. The new feature has coverage for all federal regulations and users can download, print or email the comparison, similar to how they use Statutes Compare, the popular Westlaw Edge feature that launched with the product in July and allows users to investigate the evolution of a statute. And now, within both Statutes Compare and Regulations Compare, researchers can simply navigate to the next and previous change within the document.
