Series consists of records related to the functions of the Board of Executive Directors of the International Bank for Reconstruction and Development (IBRD), International Development Association (IDA), and International Finance Corporation (IFC) that were maintained in the Bank's centralized filing system since 1946, originally General Files, then Central Files. The centralized records originated primarily from Secretary's Department as well as the Office of the President. As described in the archival history section, Secretary's Department is the custodian of Board of Directors records and proceedings but distributed certain correspondence and related documents to the Central Files while maintaining its own official files.

Records in this series include general correspondence files (1947 - 1977) concerning IBRD composition of standing committees, statements of directors, board schedules, procedural issues, information on monthly reports, and routine administrative matters. Correspondence is occasionally filed with related Board reports. While the IDA general correspondence file (1960 - 1966) is sparse, the more substantive general correspondence files for IFC (1956 - 1967) contain draft and issued Board reports regarding country membership and rules of procedure, memoranda concerning routine announcements and amendments to rules of procedure, directors' membership, formation of the IFC Board, statements and meeting summary of the IFC Directors, and investment processes. The IFC general correspondence file also contains the Rules of Procedure and By-laws booklets (1956). Individual correspondence files (1947 - 1971) consist of internal memoranda, outgoing cables and letters, and original letters primarily to and from the Bank president, secretary, and government officials regarding appointments and resignations of directors and alternates, their travel, and other administrative issues. Some individual files occasionally include the director's biographical statement.

There are also cables, memoranda, and Board reports relating to elections (1950 - 1971) and salaries and expenses (1948 - 1971), the latter which includes the report of the Board of Governors Ad Hoc Committee to consider provisions of the Articles of Agreement and By-laws relating to duties and renumeration of executive directors (1949 - 1950).

The series also includes meeting correspondence (1950 - 1971), agenda for IBRD and IDA executive director meetings (1966 - 1974), minutes of some IBRD, IDA, and IFC executive director meetings (1966 - 1974) including IFC directors' 1956 first meetings, IBRD special meetings minutes (1964), summaries, and IBRD, IDA, and IFC resolutions (1967 - 1971).

The series also includes a small volume of records relating to: the establishment and proceedings of the Bank Committee on Directors' Administrative Matters (CODAM, 1967 - 1971); agreement and administration of the Bank-Fund Executive Directors' Library (1968 - 1971); establishment of the Joint Audit Committee of the Executive Directors (1969 - 1971); and revisions of the Operational Policy Manual including the section on aid coordination and well as the approach paper on aid coordination (1970 - 1971).
