Via LLRX: “Link Rot” and Legal Resources on the Web: A 2011 Analysis by the Chesapeake Digital Preservation Group – Sarah Rhodes describes and documents the work of the Chesapeake Digital Preservation Group’s fourth annual investigation of link rot among the original URLs for online law and policy-related materials archived though the group’s efforts. Link rot” is used to describe a URL that no longer provides direct access to files matching the content originally harvested from the URL. The Chesapeake Group focuses primarily on the preservation of Web-published legal materials, which often disappear as Web site content is rearranged or deleted over time. In the four years since the program began, the Chesapeake Group has built a digital archive collection comprising more than 7,400 digital items and 3,200 titles, all of which were originally posted to the Web.
