If you plan to use the same sources for multiple course reading lists, rather than searching for or uploading records each time you use them, you can create a list of favorites. Then you can go to a course reading list and add records from your favorites list, or go to your favorites list and push records into a course reading list. 

To get to your favorites list, click the option for "Favorites" at the left of the screen in the course reserve module. 

To add records to your favorites list, click to "Add," then select to "Search the library", "Upload files", "Import references", or "Fill in Request Form". 

Once you have a list of records in your Favorites, you can go to a course reading list and look under "Add" for the "Add from favorites" option. Or, while you are in your Favorites list, you can click the three dots to the right of any item on the list and select to add it to one of your course reading lists.
