Course Reserves are easily searchable using the Library's Catalog. Once in the catalog, select the Search drop down, then click on 'Course Reserves.'
Once on the Course Reserves search page, change the search method to Instructor Name and enter the last name of your professor.
The results should display any class for which the professor has put materials on reserve. To see the reserves, select the "Availability" for the course for which you are seeking reserves. All reserves that are currently available should be visible.
