PERSISTENT URLS
What? Why?? And How???

Ever sent (or posted) a URL to students
or colleagues that just wouldn’t work?
• The URL is probably not ‘persistent’, or ‘durable’
WHAT are persistent URLs?
• A "persistent link" or a "durable URL" is a link that does
not expire or change over time.
• Persistent links are often used to link to academic articles,
search results, or e-books.
• Frequently needed with subscription based resources.
WHY use persistent URLs?
• Eliminate the “This link doesn’t work!” syndrome
• Allows you to create URLs that work ON and OFF campus
• Helps you work within fair dealing guidelines
• Keeps you within the license agreement between
Dalhousie and the publisher/vendor
• These links should work from year to year in your OWL or
course space
HOW to make them? – there are 2 ways
Method 1: from a Dalhousie Libraries database
Any of the Dalhousie Libraries databases offer either
(or both):
• A “Permalink” feature to create persistent URLs
• GetIt@Dal button that has a persistent link feature
