The Archives of the U of L produced a fascinating timeline. "The University of Lethbridge Timeline is a chronological history of events from its conception in 1966 until present day."
Update 2020: the link to the timeline is no longer active. Responsibility for the timeline was moved to University Advancement (from the University Archives) in 2020 at which time, the link went dead. We are retaining this entry as a reminder to look periodically for a new link to this excellent history.
