How to Use This Guide

Frequently Asked Questions

Why do some fields use multiple styles?

Fields that sit at the intersection of two traditions — political science between Chicago AD and APA, linguistics between MLA and APA — often see real variation between programs, sometimes even between professors within the same department.

Is there a global "correct" answer for interdisciplinary programs?

No — interdisciplinary programs (like many nursing DNP or public health doctorates) typically pick one style as a program-wide standard, most often APA, regardless of which fields the coursework draws from.

Do citation style requirements change between undergraduate and graduate work in the same field?

Rarely for the style itself, though graduate and doctoral work often enforces stricter formatting precision and expects more source diversity within the same required style.
