The Hawaiian collection covers a broad range of topics, all concerning Hawai'i: its culture, history, people, and environment. Some of the material dates back to the early nineteenth century. The Lum Hawaiiana Room is named in memory of Lum Yip Kee, Lum Chang Tai, Y.T. Lum and Louise Lee Lum.
Started as a loose collection of gifts, records and valuable materials handed down between administrations and librarians for decades, the Punahou Archives began to formalize in the 1950s. It is comprised of school publications, photographic and multimedia images, artifacts, institutional records and manuscript collections which explain the historical events, growth and development of Punahou School. Managed by a professional archivist, the Archives is available for use by the Punahou community and private research by appointment.
