It is a good idea to use a citation tool to help you with your citations. You can use either a citation generator or a citation management tool. Citation generators are great for quick projects like short papers with just a few resources. However, you should always check generated citations for errors (tip: there are almost always errors, especially with capitalization and use of italics).
A good citation generator is Zbib. Watch this quick tutorial video about how to use it.
For large projects like research papers or capstone projects, you should use a citation management tool. A good, free citation management tool is Zotero. More information can be found in this Zotero guide.
