Thanks to a great question from Rob Fuller, Webmaster for Vanderbilt's College of Arts and Science, we wanted to share a great tool-tip with everyone!
By adding ?is_archived=1 to the end of your calendar's URL, you can create a new URL that displays a list of archived events in the same calendar view you are used to instead of having to go in and link to each individual archived event!
(NOTE: This also works with the News tool for archived articles!)
http://www.vanderbilt.edu/biosci/seminars - shows The Department of Biological Sciences' FULL calendar
http://www.vanderbilt.edu/biosci/seminars?is_archived=1 - shows ONLY those events which have been marked as "Archived"
