Perma.cc is an archival tool that helps scholars, journals, courts, and others avoid linkrot by creating 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 the law library can sponsor individual user accounts of faculty, staff, or students affiliated with the USC Rice School. Sponsorship by an academic institution simply means that the user does not have a monthly limit on their Perma captures. Only the individual sponsored user and the law library "registrars" have access to the content of a sponsored account.
Perma can also be used to create sponsored organizations. Once the organization is created, one or more faculty, staff, and students can be associated with it, making it perfect cooperative work that requires access by multiple people. For example, an organization might include a faculty member and their research assistants, the members of a student group such as the editorial board of a law journal, or even all of the faculty support staff assisting faculty prepare scholarship for publication.
The roster of the users and organizations sponsored by a given institution 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:
