Perma.cc

Perma.cc is a web preservation service that helps scholars, journals, courts, libraries, and other organizations protect the online sources cited in their work. As websites change, disappear, or are altered, citations can lead to broken or unreliable pages—a problem known as link rot. Perma.cc addresses this by creating permanent links to unalterable records of web pages, helping readers access the material as it appeared when captured.

Using the service is straightforward: users copy a page’s URL, add it to Perma.cc, create a Perma Link, and use that link in their citations. Each record keeps its content and address unchanged, even if the original website later changes. Users can also annotate or delete a record after it is created. Perma.cc offers accounts for individuals, libraries, courts, and other organizations, along with guidance, frequently asked questions, and an API for developers. Built and supported by libraries, the service is trusted by more than 150 journals, courts, and universities to help preserve the reliability and integrity of citations over time.
