“The Chesapeake Project Legal Information Archive has completed its third annual analysis of link rot among the original URLs for law- and policy-related materials published to the Web and archived though the Chesapeake Project. The Chesapeake Project was launched in 2007 by the Georgetown University Law Library and the State Law Libraries of Maryland and Virginia as a collaborative digital archive for the preservation of important Web-published legal materials, which often disappear as Web site content is rearranged or deleted over time. More about the Chesapeake Project. In the three years since the archive was launched, the Chesapeake Project law libraries have built a collection comprising more than 5,700 digital items and 2,300 titles, all of which were originally posted to the Web. 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 Project’s digital archive. In some instances, a 404 or “not found” message indicates link rot at a URL; in others, 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. All of the Web resources described in this report that have disappeared from their original locations on the Web remain accessible via permanent archive URLs here at legalinfoarchive.org, thanks to the Chesapeake Project’s efforts.” [Sarah Rhodes, Digital Collections Librarian, Georgetown University Law Library]
