Perma.cc is a service that helps prevent link rot by preserving the content of web pages as they existed at the time the Perma.cc link was created. Perma.cc makes a copy of the target web page, deposits it into the Perma.cc collection, and returns a unique, citable URL that points to the preserved record.
Perma.cc is not a web archiving tool. Perma.cc doesn’t attempt to crawl web pages in full and only saves a copy of the single page that the user wants to cite as a PNG screenshot and a Web ARChive file (WARC).
How does it really work? Is it reliable? Learn more about Perma.cc.
See the Perma.cc User Guide for more information and guidance.
Cite both the Perma.cc URL and the original URL.
An example from the Harvard Law Review:
4 See, e.g., Charles P. Pierce, This Cannot Be the Way Occupy Ends, ESQUIRE: POL. BLOG (Nov. 17, 2011), http://esquire.com/blogs/politics/occupy-wall-street-violence-6575448, archived at http://perma.cc/48VC-ZS62 (bemoaning protestors' "reciprocal violence" and arguing that the protest "can't end in images of bleeding cops and tossed barricades").
Always follow citation styles. For guidance on this see our Citing Sources guide.
