The PDF, above, is a guide developed from the Chicago Manual of Style.
For general information about Chicago -- such as formatting and notes -- refer to Purdue's Online Writing Lab. It even has a sample paper that shows you how the paper should be formatted.
If you would like me to help you get set up with Zotero, a free Citation Reference manager, make an appointment to see me and bring your laptop. You can insert endnotes in Microsoft Word as Well as Google Docs. Note that in Fall 2019 Zotero is not working with the Safari 13 browser (see compatibility).
