These are links to major style guides which can help with citations
There are a lot of citation management tools available free to students. The librarians at Knox college encourage students to use Zotero, although check with your professor as they may wish you to use a different tool.
Do NOT use tools like easybib, citation machine, or son of citation machine. These tools frequently give incorrect citations.
Citing sources is an essential part of participating in the "scholarly conversation." It's a way of showing the work you've done as well as giving proper credit. If you need help with citations you can ask any of the librarians for help. The sooner you ask for help the more we will be able to do so please come in early.
