From at least 1872 until the early 1890s, when the Badger Yearbook seemed on pretty firm footing, most classes at the University of Wisconsin created a class album, providing invaluable sources for the early history of students on campus. All of the albums have photographs of students, and sometimes faculty members. Also, many of the albums have autobiographical essays, student responses to various questions, and some include a history of the class (often written by the class historian). Together, the class albums and the Badger Yearbooks provide a nearly continuous history of students at the University of Wisconsin-Madison.
