If you are teaching a course that used Readings & Resources in the past, you can duplicate that list and use it as a starting point for the current course.
From the initial Readings & Resources screen, Select Existing List.
You will see a list of your available lists. Select Duplicate List for the one you want.
Under Advanced Settings, you can select which elements of the list you want to duplicate.
If you are teaching multiple concurrent sections of a course, you can use the same list for all of them.
Use the Add Another Course link to add.
The default view in Canvas shows the Readings & Resources list associated with the course you are currently in. But you can use the backwards-pointing arrow to view all your lists across courses, including those that may not be associated with a course.
Here you can view all lists, and manage them with the three-dot Lists menu.
Favorites is a collection of items from Library Search that is separate from your resource lists. When searching within Readings & Resources or in Library Search, you can save items to Favorites for later use. You can also “Save as favorite” an item that you have already added to a list. Using Favorites can be an efficient way to add the same item to multiple courses.
