There are several free citation management software applications. The most popular of these applications are Zotero, Mendeley, and EndNote.
These applications will help you organize, share, export, import, and modify 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.
To download these applications, or plugins, follow these links:
The WSU Libraries do not endorse any particular citation management application. That said, from experience, I've found there to be a little less of a learning curve with Zotero and Mendeley as opposed to EndNote.
Although I use all three applications, I tend to use Zotero the most.
Here's the quick start guide link which will get you going with Zotero.
