The Discovery Catalog also has a citation tool which users can utilize to create system-generated citations. From inside the record, you can find Cite in the upper-right corner next to the Link option.
The citation generator will appear as a pop-up box. Inside the box, you will choose your citation format from the drop-down menu (i.e. MLA), and it should automatically generate a citation below. Always make sure to check for errors in any system-generated citation before using it in an assignment.
