Where can I find old course outlines and calendars?
Undergraduate course calendars (academic year 1999-2000 to present) are available online as PDFs from the registrar's Academic Calendars website.
Hard copies university course calendars for years prior to the 1999-2000 academic year are available in the Archives and Special Collections on the third floor of the Scott Library.
While ASC has almost a complete set of undergraduate, college and graduate course calendars, they do not have anywhere near a complete run of individual departmental mini-calendars / handbooks which contain descriptions for some summer and "special topics" courses offered by departments. See the complete listing of what is available.
Note: The archives has no course syllabi.
