Webpages are frequently modified or taken down. This has been a major problem in the past because many of the URLs that appeared in citations would often be "dead links" by the time an article was published. Perma.cc addresses the problem of "link rot." Perma.cc allows users to preserve links by making archival copies of webpages. As a result, future readers will always be able to see what a webpage looked like at the time when the Perma link was created, even if the webpage is subsequently changed or removed. Perma.cc has allowed authors and student editors to feel more confident about relying on electronic sources in citations.
To create a Perma link for an URL on Perma.cc:
Step 1: Log in to your Perma.cc account.
Step 2: Copy and paste the URL of the link you wish to preserve and select the appropriate folder where this link should be saved (e.g., your journal's folder). Click the blue "Create Perma Link" button.
Step 3: After a few seconds, you will see your Perma.cc record. You should add the Perma link URL (shown in blue near the top of the screen) into the citation by placing it in brackets following the URL, pursuant to Bluebook Rule 18.2.1(d). The Perma link will become permanent after 24 hours.
Note Regarding Private Perma.cc Records: Occasionally, Perma links will be marked as private records, which means that only the creator of the link and the organization that controls the Perma.cc account will be able to see the content at the Perma link. The image on the left illustrates what you and your journal will see when you log in to your Perma.cc account and follow the Perma link URL, while the image on the right illustrates what anyone else will see if they follow the Perma link. You should still generate Perma links for this content so your journal can retain a record of the source.
