So, you have looked at your primary sources on microfilm and now you need a way to cite them in your paper. How do you do this?
There are two basic steps to citing microfilm:
1. Cite your primary source
2. Add information about the microfilm
You need to indicate in your citation that you were using a microfilm so readers know you were not looking at the original document.
Yale Writing Center has a great page with examples that will help you get a feel for what citing a document on microfilm will look like in different styles.
