Chicago (Turabian) style

The Chicago Style was developed by the University of Chicago. It presents two basic documentation systems: notes-bibliography and author-date. Please check your unit guide to see which system is required.

In-text citation

  • Notes-bibliography consists of two parts: a number in the text and a note either at the bottom of the page (footnote) or at the end of the paper (endnote). Notes are numbered sequentially beginning with 1., throughout each article, chapter, or paper. The numbers in the text must be in superscript and should follow the punctuation. The note should have a normal, full-sized number.
  • Author-date consists of the author's last name and the year of publication of the work cited. No punctuation is used between the name and the date.

Reference list

The reference list should be ordered alphabetically by the last name of the first author of each work. References with no author are ordered in the reference list alphabetically by the first significant word of the title.
