The American Medical Association (AMA), both a professional organization and a publisher, establishes citation style rules to encourage accuracy and consistency in scholarly communication.
This guide was created as a supplement to the AMA Manual of Style (11th edition) for our students at National University and addresses the most common style questions and formatting issues. For more specific information, please refer to directly to your AMA Manual of Style.
