This collection consists of notebooks containing diaries of the Atlantic Meeting, Washington, Quebec, Cairo and Yalta conferences. Green tends to record events from his own day but when relevant these include encounters with Churchill and other key figures.

The collection relates to Charles Eade's connection with Sir Winston Churchill. It includes Eade's diary of meetings with Sir Winston; biographical material about Sir Winston and Sir Winston's own speaking notes for his speech made on 20 June 1940 which Churchill gave to Charles Eade.

The material covers much of Lord Duncan-Sandys public life. Papers, reports and correspondence document the ministries in which he served and there are also constituency correspondence, speeches, publications, press cuttings and photographs. A number of papers exist relating to his involvement in the campaign to restore Capital Punishment, the European Movement and the Civic Trust.

The collection chiefly compiles Lady Onslow's personal letters written to her parents and sister "Jim" from her travels in Churchill's service. They provide first hand evidence of her experiences and include lively recollections of Churchill, descriptions of her work and colleagues, and descriptions of journeys, accommodation and surroundings. The letters are supplemented by a small number of photographs and other mementos.

The material held at Churchill Archives Centre mainly consists of Colville's diaries. They provide an insight into the decision-making of three Prime Ministers and the meetings held with other top officials, as well as the lives of key figures during World War II, and its aftermath.
