There are any reference management tools useful for creating bibliographies and keeping track of your references.
MMLL students often use:
Zotero - The only research tool that automatically senses content in your web browser, allowing you to add it to your personal library with a single click.
Mendeley - Generate citations and bibliographies in a whole range of journal styles with just a few clicks.
EndNote - A reference management software that enables you to store and manage your references. It will then create bibliographies from these references automatically.
