What does do? prevents link rot.

Why does exist?

Links to digital sources can fail: the information at a URL can be modified or deleted and the intention of a reference can be lost. This isn’t necessarily a big deal for a basic blog, but it makes a difference for scholarship, legal writing, and any instance where the information cited is part of the logical framework of the content. prevents this failure — called link rot — by archiving a copy of the digital source and preserving it in perpetuity through our network of libraries and institutional partners.
