The series consists of subject files covering the operations of the Committee on a day-to-day basis. These include records of meetings of the Committee President with various members, with the President of the Bank and the Managing Director of the International Monetary Fund (the three together are known as the Troika), and with the Intergovernmental Group of Twenty-Four on International Monetary Affairs. There are records of administrative matters such as governance and membership, budgets, work programs,and correspondence with other multi-lateral international development agencies. Other files contain information on topics of interest to the Committee, such as health, environment, and debt issues, while still others are speeches, general correspondence, and the publication of a pamphlet for the tenth anniversary of the Committee.

When this series was in active use, it was the heart of the Development Committee secretariat operations, according to former Executive Secretary Peter Mountfield. It is an essential resource for understanding the scope and operations of the Development Committee during its first two decades.
