Planning the Coronation: the Coronation ceremony, with other State ceremonials, falls under the jurisdiction of the Earl Marshal, one of the Great Officers of State. The Officers of Arms, or heralds, act as his Staff. They also maintain the official records of coronations, which are held in the archives of the College of Arms. The Coronation service of 1953 was planned and arranged by the Earl Marshal's Office.
On display at the College of Arms are facsimiles of documents in the College archives relating to the Coronation of Her Majesty Queen Elizabeth II. Included are examples of preparations for the ceremony, photographs of the service itself, and subsequent analysis of the proceedings by Garter King of Arms for the use of future generations. Also included are photographs of artefacts owned by the College which were used in the preparation for the service and at the ceremony itself.
Some of these items can also be seen on the College of Arms website: http://www.college-of-arms.gov.uk/news-grants/news/item/84-planning-the-coronation
