The Chicago style is used most frequently by historians, and the 16th edition is the most recent and comprehensive. A simpler version of the Chicago style intended for students is offered in the Kate Turabian's A manual for writers of research papers, theses, and dissertations : Chicago style for students and researchers. This manual, which presents what is commonly known as the "Turabian" citation style, follows Chicago patterns but offers slight modifications suited to student texts.
