Seattle Prep will celebrate its 125th anniversary next fall. Establishing an archives fulfills a need for a program dedicated to the collection, organization, and preservation of items that document the history of Seattle Preparatory School. The archives will connect the present Seattle Prep community with the past, by making these materials accessible, and promoting their use for publications, exhibits, and research. This project began with a preliminary inventory of historical items throughout the Seattle Prep campus, in order to plan for the space and supplies needed for proper archival storage. Boxes of items were moved onto new shelving and prioritized for future processing. Archival policies were drafted including a Mission Statement, Collection Policy and Access Policy. Finally, a Long Term Plan was drawn up, giving direction to archival work that will be done, with a unique focus on student involvement.
