RefWorks allows you to simply create bibliographies out of your references in almost any citation styles (MLA, APA, etc.). Make sure your citations are complete, otherwise your bibliography won't be correct.
From either the "All Documents" view or from within a folder or subfolder, select the references you want to include in your bibliography.
From the top menu select the quotation marks and "Create bibliography."
Select your preferred citation style from the drop down menu at the top or search for your desired style.
Use the "Copy to Clipboard" button to copy your works cited and paste it into your document.
