A particularly important high school artifact is the yearbook, which records everything that happened in the previous academic year. As with the student newspaper, the yearbook is a student-run project with the staff responsible for the photography and design.
Yearbooks are offered for younger students as well but they carry a special importance for high school students, with the yearbook for one's last year being particularly important. Most of a yearbook is dedicated for the students who are about to graduate and the yearbook staff is comprised mostly of seniors.
Every yearbook contains pictures of every student in the school. Most of these are pictures taken at in-school picture day, but graduating seniors usually elect to hire a professional photographer instead. Aside from better quality, these pictures can highlight the interests or achievements of the student in question.
A yearbook will also contain pages dedicated to every club, sports team and school event. Most will also contain pages for student life which, as with the paper, include in-jokes and cultural touchstones.
There are many additional traditions related to yearbooks. Since most of the graduating seniors aren't going to see their classmates for a long time, they will often write messages in each other's books. Some yearbooks even include extra blank pages specifically for this.
