Create Accessible Links
There are a number of technical concerns for the accessibility of links. Those matters are handled by Princeton's instance of Drupal. It is recommended configure your Drupal site under the configuration of the user interface where you can add icons to all link types. These icons will be read aloud to a screen reader to provide context to the links in your content.
