At Kent School, your work in History will require citations and formatting according to The Chicago Manual of Style, or CMOS. Chicago has strict guidelines for margins, font, spacing, pagination, etc.
While it is always a good idea to follow these guidelines, your teacher may not require the exact specifications of Chicago formatting. Check with your teacher, and also review the sample papers available to you through the ARC and Library.
Remember to follow the rules in the History Research Guide when you write a paper for the History Department.
