The Chesapeake Digital Preservation Group is releasing the results of its fourth annual analysis of link rot among the original URLs for law- and policy-related materials published to the Web and archived by the Chesapeake Group.

The analysis also explores the prevalence of link rot among top-level domains. A detailed summary of the study is available at http://legalinfoarchive.org/.

For this study, the term "link rot" is used to describe a URL that no longer provides direct access to files matching the content originally harvested from the URL and currently preserved in the Chesapeake Group's digital archive. In some instances, a 404 or "not found" message indicates link rot at a URL. In other cases, the URL may direct to a site hosted by the original publishing organization or entity, but the specific resource has been removed or relocated from the original or previous URL.
