Citation management tools can help store, organize, and format citations. Many tools can automatically insert formatted citations into documents. Some of these tools include:

• RefWorks (available through the Penn Libraries)
• Zotero
• Mendeley
• EndNote

For more information on using these bibliographic tools, please see our Citation Management Guide.  

Purdue's Online Writing Lab has detailed instructions on formatting citations according to citation style, including MLA, APA, Chicago, and other styles.
