To help instructors keep track of how much readings are being used, it is possible to check the usage statistics for the posted readings.
When you are logged in to my.torontomu, look on the Course Menu page for the Course Readings Usage, link and click it.
The Usage column on the right side of the page will show how many times a document was opened.
The Show Detailed Usage Link will tell you the dates on which an item was viewed, as well as how many times it was viewed on each date.
