Websites change, go away, and get taken down. When linked citations lead to broken, blank, altered, or even malicious pages, that’s called link rot.
Link rot affects everyone who cites links
Over 50% of cited links in Supreme Court opinions no longer point to the intended page. Roughly 70% of cited links in academic legal journals and 20% of all science, technology and medicine articles suffer from link rot.

Link rot destroys the integrity of your citations
Links start healthy. New citations have been vetted and verified.
After one year. After a year, over 20% of cited links may be dead or otherwise inaccessible.
After five years. After five years, the situation is much worse — over 50% of cited links can be affected.
As time goes on. Link rot is inevitable and rarely reversible. The longer the wait, the more likely a link will have rotted.
A Perma Link is a reliable, unbreakable link to an unalterable record of any page you’ve cited. It’s a time capsule for a web page, which your readers can easily access.
We’re committed to preservation

This decay is called “link rot.” Perma.cc helps scholars, journals and courts prevent link rot by creating permanent, reliable, unalterable links to the online sources cited in their work.
