Illinois Institute of Technology yearbooks under the titles Polygon, Integral, and Unified.

Contents and organization of the yearbooks vary from year to year as student writers, photographers, and editors chose to include or exclude information of students by class year, members of faculty and administration, academic program, extracurricular activities, student organizations, and sports. Generally, earlier yarbooks include more text and image identification, later ones contain more photographs, but individuals are frequently unidentified. Most yearbooks included photos of Seniors. Some yearbooks include group photos of Juniors, Sophomores, and Freshmen, in some cases, only a class roster is listed. None of the yearbooks include information about graduate programs or students.

IIT did not publish yearbooks from 1990-1997 and 1999-2004.
