Course: History 1 Mexico: Citing sources

When to cite a source


You must cite all works that have contributed to your knowledge, understanding, and analysis of your research topic. You must cite any work that you:

  • Summarize: Any arguments or information that you synopsize 
  • Paraphrase: Any text that you rewrite in your own words
  • Quote: Any text that you include in quotation marks must be cited and footnoted

Below are examples of various types of citations in Chicago style, which is used in History 1. You are welcome to write them by hand or to use Noodletools to walk you through the process. Noodletools is a reliable way to make sure that all of the necessary information is included. If you need help logging into Noodletools ask one of the librarians.

Why is citing your sources important?

  • It gives credit to the people who did the original work.
  • You avoid plagiarism.
  • It can lend credibility to your arguments.
  • It can help your readers find the source themselves.

What is plagiarism?

Plagiarism is when you steal someone else's words or ideas and pass them off as your own.

You can avoid plagiarism by citing your sources, which lets your reader know that the words or ideas are borrowed from someone else, and gives them a way of finding the original source.

Creating an annotated bibliography

How do you create citations?

Remember to record the following pieces of information from your sources so you will have them when it's time to create your citations.

  • Author
  • Title (both article and book/journal where applicable)
  • Date of publication (or date you viewed it on a website)
  • Publisher (for books)
  • Place of publication (for books)
  • Volume number (if applicable) and page numbers.
  • Web address (if applicable)

Your teachers would like you to use Chicago style citations in your research paper. This means there will be footnotes in the body of your paper and a bibliography listing sources at the end of your paper.
