A Persistent Uniform Resource Locator (PURL) is a type of web address that is designed to be stable and to provide a long-lasting identifier for digital resources, even if their actual location on the internet changes. PURLs are often used in digital libraries, repositories, and other contexts where the permanence of a resource's location is important.
