There are many online resources for viewing past yearbooks from 1973 and other years, such as Ancestry.com and Classmates.com. Classmates states that it hosts 300,000 yearbooks from over 200,000 schools. ThisOldYearbook.com is an online store that specializes in buying and selling old yearbooks. TOY includes elementary school, middle school, junior high school, high school, college and university, and military class yearbooks.
Ancestry.com archives yearbooks and other school-related records as they are often rich in detail and can be useful for genealogical research. The records can include personal or family members' information such as clubs, activities, events, classes and photographs.
Some schools provide free access to digital copies of their yearbooks on their websites. Schools may also keep hard copies of their yearbooks for student and faculty use, and many public schools donate their yearbooks to local libraries for storage and safekeeping. Contact your school or organization's records department or library to ask if they allow access to their yearbooks to the public.
Individuals looking for yearbooks from a specific year and school can contact persons who were students or graduated from the institution at that time. Many former students retain their yearbooks and records from educational institutions. Faculty and staff members may also possess these records.
