Writing citations and bibliographies can be tedious and time-consuming. Luckily, there are some great free tools that will create them for you. Such tools will let you collect a set of sources and then drop them into your paper as you type. They will also let you automatically convert from one citation style to another. We recommend Zotero (see our guide).
If you’re using Microsoft Word to write your paper, it has some of its own citation features. Word also works nicely with Zotero.
