Dissertation by Tomoko Ito ドルトン・プランにおける「自由」と「協 同」の教育的構造 (Educational Structure in the Dalton Plan as "Freedom" and "Cooperation") Tokyo: Kazama Shobo, 2007

The Dalton School’s archival records–other than widely distributed records, such as school publications and publicity materials–are available only to the current Head of School, the office of origin, and the Dalton School Archives staff. Access by others will be given consideration when a written request is presented to the Archivist and written approval has been obtained from the appropriate individual in the office of origin or the Head of School.
