Streaming videos in Kanopy and Swank databases are licensed for a year (or occasionally, multiple years). Depending on when the license began, the license may expire during the middle of an academic year or the mid-semester. You may ask the subject librarian or Perimeter campus librarian about the expiration date and whether the license can be renewed. You may also check the expiration date yourself as follows:

In Swank, the expiration date is located immediately below the film in the Swank portal. Expiration dates are also listed in the library catalog record for each film. 

For Kanopy films, you can check the expiration date in the library catalog.

• Search the library catalog for the title of the film. You may need to limit results to "Full access online" and "Video."
• In your results, look for the item that says "Kanopy" in it -- once you find it, click the Online Access link in the record.
• In the View Online area you'll see the license expiration date. The screenshot below shows a film with the expiration March 19, 2022. 
• Kanopy film licenses can usually be extended by faculty request. Contact a librarian by subject or Perimeter campus to request an extension or use the Purchase Request Form, noting in the comments that the request is for a renewal.
