Breaking Down Link Rot: The Chesapeake Project Legal Information Archive’s Examination of URL Stability: “This guide for researches by Sarah Rhodes focuses on the highly significant impact of “link rot”, which refers to the loss or removal of content at a particular Uniform Resource Locator (URL) over time. When an attempt is made to open a documented link, either different or irrelevant information has replaced the expected content, or else the link is found to be broken, typically expressed by a 404 or “not found” error message. This is not an uncommon occurrence. Web-based materials often disappear as URLs change and web sites are changed, updated, or deleted.”
