References in Word are stored on your computer's hard disk. If you want to work with them on another computer, follow these steps to find the file:
Microsoft Word has a simple built-in reference function at the References tab. Here you can manually enter references and refer to them in the text and create a bibliography in the most common styles (APA, Harvard, MLA, etc). The built-in function in Word is suitable if you have a limited number of references and if you don't need to have access to your references from multiple computers.
