Citation Management Applications
There are several free citation management software applications that assist with organizing and exporting citations. You can learn more about those applications on this WSU guide. Such applications although helpful, do operate on a garbage in/garbage out principal. These applications are free and are quite similar in use. You can export citations easily from one application to the next.
Clarivate (the makers of EndNote) have many great tutorials to help get you started.
