A citation is important for many reasons.
Plagiarism is taking text, ideas, images, sound recordings, or other creative expressions that belong to someone else and representing them as your own. When you effectively cite your sources, you avoid plagiarism.
For more resources and information, see the Citations and Plagiarism guide.
Remember, many online resources now provide citations formatted for your Works Cited or References page. Look for them when using databases and online encyclopedias. You can often find them by clicking on the "Cite" tool. However, you should always be aware that these citations are produced with algorithms that often create mistakes. Double check every citation, and remember that you are ultimately responsible for the accuracy of your citation format and content.
Don't forget to include in-text citations too.
