This series contains internal correspondence sent and received by President Wolfensohn from the beginning of his tenure in 1995 to the end of 1999. Beginning in 2000, internal and external correspondence was filed together physically and managed together in a single sequence in the document management database. Internal and external correspondence from this period have not been separated, resulting in internal correspondence from 2000 to 2005 being arranged together with external correspondence elsewhere in this subfonds.

The majority of the internal correspondence in this series is initiated by incoming correspondence. Most of the correspondence is with the World Bank Group's (WBG) senior management, including managing directors and vice presidents, although correspondence involving other upper-level WBG staff is also included. Correspondence takes the form of memoranda and printed-off emails and can sometimes include accompanying information in the form of reports and informal notes.

A small amount of communication in this series was initiated by President Wolfensohn or the Office of the President (EXC). The purpose of most correspondence initiated by the president or EXC was to seek information, updates, or opinion from Bank Group staff.

Upon receiving or initiating a piece of correspondence, the item was logged by EXC's correspondence unit in the document management system, EnCorr, and given a reference number. With just a few exceptions from the beginning of President Wolfensohn's tenure in 1995, a profile for each internal correspondence was not created as it was for external correspondence. Instead, the database reference number was handwritten on the first page of the correspondence. Instructions on how to handle or proceed with correspondence, if included, are provided in the form of handwritten notes added to the first page of the correspondence package or provided in additional email or memoranda that is stapled to the correspondence. In some cases, correspondence in the form of memoranda or printed-off emails reach President Wolfensohn who then made handwritten responses directly on the initial correspondence; his notes are then included in an email response to the original sender.

The topics covered in the correspondence are varied and include: updates on WBG projects; geopolitical and country economic updates; submission of draft reports for review; discussion of staffing, appointments, and other matters related to personnel management; summaries or minutes from meetings with WBG departments; and media engagement (in the form of sharing media clippings or preparation for media engagement). Correspondence with the Board of Executive Directors and with individual executive directors is also included.
