This series contains copies of the outgoing letters, memoranda, and facsimile messages from the chief and other members of the Policy Development Unit (PRDPD). Included with the outgoing messages are a few incoming memoranda from the Director of the Policy and Review Department (PRDDR) and from the Senior Vice President, Policy, Research and External Affairs (PRESVP). Much of PRDPD's correspondence concerns the scheduling of review work on policy papers, comments on draft policy papers, coordination of PRE policy matters with the Board, and the compilation of information for the inventories of policy products. PRDPD had responsibility for managing the PRE Committee, and this series includes memoranda transmitting schedules, agenda, and minutes of meetings of the Committee, some of which include copies of the papers to be discussed by the Committee. Also included are 1991 agenda of the New Products Working Group and materials for the first meeting (September 4, 1991) of the Working Group on Military Expenditures.
