This collection contains material relating to the history of the houses and their pupils. Each series is focused on a different house and many contain rich and detailed photographic records of houses year by year. Some houses are more detailed than others.

Other highlights of this collection include house handbooks, which help to induct a pupil into a house and its daily routine; photographs of daily life, including house events and leisure time; and administrative documents such as house diaries which record the calendar of house events, achievements of pupils, and accounts of incidents.
