What is year book?

A yearbook is an annual publication that chronicles the events and activities of a school, college, or other organization over the past year. Yearbooks typically include photographs, articles, and other information about the school or organization, as well as information about the students, faculty, and staff. Yearbooks are often used as a way to document the history of the school or organization, and they can also be used as a way to promote the school or organization to potential students or members.
