What Are Persistent Links/Permalinks (PURLs)?
Persistent Links, also known as Permalinks, PURLs, or Stable URL’s, are URL’s that link directly to electronic resources such as journal articles, ebooks, or databases. These links remain stable and consistently connect to specific resources like the ones mentioned above. It is critical to include persistent links while steering students to materials in course syllabi, within learning management systems such as Blackboard, or within a e-Reserves system. This will create an easy and seamless way for students to access online materials without any problems or interruptions.
Linking to Journal Articles
Most journal online archives have an icon for persistent links somewhere on the page of the article. Often times this icon is a clipboard image or a chain link image. Clicking on the icon will create the persistent URL for that particular resource.
** It is important to remember to add the proxy server prefix to the beginning of the persistent URL. For example:
Green= proxy prefix Blue= persistent URL
Below are instructions on finding persistent links in the Naval War College Library’s most used electronic resources:
What if the electronic resource I found an article in doesn’t have a persistent link icon?
Many online resources do not have an easily available persistent link. Many times you can find a stable URL listed in the abstract of an article, on the bottom of the page where it lists the location the article was retrieved from, or through a DOI—which is a unique alphanumeric string assigned to an individual digital object. If none of these options are evident in a database, simply copy and paste the URL in the web address box—just keep in mind that this URL may not stay stable over a long period of time.
Linking to Electronic Resources
There may be instances where you would like to link to specific electronic resources in general, without linking to a specific article. To create a persistent link to a database:
- Click on the "Electronic Resources A-Z" link on the library homepage.
- Find the resource on the A to Z list. Click on the "share" icon to copy and paste the persistent link.
