When a citation to a web resource no longer works, it's referred to as "link rot." This phenomenon can be a serious problem for scholarly and legal works. For example, over 50% of links cited in US Supreme Court opinions no longer refer to the intended content. Perma.cc provides a web archiving framework designed to mitigate this problem. In addition to citing an original source URL, authors may use Perma.cc to create an archival copy of the page they were viewing. This archival copy will be preserved both immutably and indefinitely. Individuals without an institutional affiliation can create a free account that can archive ten links per month. Accounts with no quota are available to faculty members, journal publishers, and courts. Perma.cc works in any modern browser.
