Perma.cc is an archival tool that helps scholars, journals, courts, and others create permanent records of web sources cited in opinions and scholarly articles. Perma captures what the page looks like at a given moment in time, regardless of later changes. Perma also has the ability to hold uploaded screen captures if there is a barrier to the normal archiving process. Citation can be made to the archival copy, preserving the artifact even if the original page is subsequently altered or removed.
The University of South Carolina Law Library has an institutional account with Perma.cc. This means that faculty and journals affiliated with the USC School of Law can have 'organizations' associated with the institutional account. An organization can be a single faculty member or can include the faculty member's research assistants, at the faculty member's discretion. It can also be a student group such as a law journal where the members are the editorial board of the journal.
The roster of the associated organizations is controlled by the account's "registrars" who have the power to create associated organizations and add and remove users. Registrars are automatically members of all of an account's organizations. The USC law library's registrars are some of its librarians.
When a user creates a Perma.cc link, Perma.cc archives the content of the referenced web page and generates a link to the archived record of the page. Regardless of what happens to the original source, the archived record will always be available through its Perma.cc link.
See the individual instruction pages for more information on how to use Perma.
Bluebook Rule 18.2.1(d) encourages archiving Internet sources in order to prevent link rot, using both the Perma Link and original URL in the citation. A citation would look like this:
