How does Perma.cc work? You give Perma.cc the URL of the page you want to preserve and cite. Our software visits that URL, preserves what's there, deposits it into our collection, and gives you a unique URL (e.g. "perma.cc/ABCD-1234") - a "Perma Link" - that points to the record in our collection. You then can use that Perma Link in your citation to give readers access to a stable, accurate record of the source you referenced, even if the original disappears from the web.
how does this compare to other web archive tools? is it really "permanent"? any disadvantages of this tool?
