Are There Tools To Help Me With Citations?

There are some free tools available, such as Zotero and Son of Citation Machine.

Other tools like EasyBib will give you some citation help for free, but you will have to pay to get more features or citation styles.

Tools such as these can help you to correctly format your citations, but they are not perfect!
You still have to know what correctly-formatted citations should look like, for the particular style you are using.
