These guidelines are based on the advice from The Chicago Manual of Style (CMS), 17th edition, published in 2017. Design and layout of materials is based on Diana Hacker's "Research and Documentation Online, 5th edition" accessed March 2014. This style guide is most often used in courses for History, Humanities, Literature and the Arts.

Chicago has two systems of documentation. One uses Footnotes (notes at the end of the page) or Endnotes (notes at the end of the paper) to cite materials, along with a Bibliography at the end. The other system, Author-Date, uses parenthetical in-text citations and a Bibliography at the end. It is referred to as Author-Date because the in-text citations use (Author's Last Name Date, Page Number) format; ex. (Krahmer 2015, 192).

The Chicago Manual of Style uses two formats: Notes & Bibliography and Author-Date. Make sure you are using the correct format, as there are many differences between them. To view the entire Style guide, you can visit the online version (required Colgate login) or ask for the print copy in the library.
