Student with iPad. By UBC Library Photostream from Flickr

PURLS, or Persistent URLS, are links to specific web pages that remain stable over time. Many people don't know that some urls are "session-based" and only work for the duration of your search session. If you try to access a session-based url after you log-off, navigate away from the page and/or several hours later you will get an error message instead of the page you were expecting.
