This series consists of circulars, clippings, course work, plans, proposals, syllabuses, class lists, and schedules for programs and proposed programs sponsored or administered by the IIGS. The material dates almost exclusively from 1950 through the late 1970s, when the Institute's major programs were in English, library science, and Psychology. The material is arranged alphabetically by program name.

Related material can be found in Series XII - Reports, the correspondence of the Director with the Corresponding Secretary in Series II, and in the Minutes of the Corporation and its committees in Series VIII.

This series is divided into seven subseries, Boston Secretary, Clerk, Corresponding Secretary, Director, President, Treasurer, and General.

Boston Secretary consists of the correspondence files of the Corporation's secretary in Boston, Mass. The material is primarily corporation membership record-keeping and is divided into six sections: Clerk, Corresponding Secretary, Director, President, Treasurer, and General. Correspondence with all individuals other than those holding positions in the first five sections is filed in the last section, General.

Correspondence files of the Clerk of the Corporation appear in the second subseries filed chronologically. The bulk of the material pertains to Corporation activities in the U.S.

The Corresponding Secretary (now known as "Executive Secretary") is the Corporation's main link with the staff in Spain. The correspondence contains ongoing reporting of the activities of the Institute in Madrid, extensive material on the selection of staff and scholarship students, and on arrangements for IIGS foreign scholars' study in the U.S. The files are divided into seven sections: Boston Secretary, Clerk, Director, Liaison Committee, President, Treasurer, and General. As with the Boston Secretary's files above, the 'General' section consists of correspondence with all individuals not covered in the preceding sections. The Liaison Committee section contains correspondence to members of the committee which assumed the duties of the-Corresponding Secretary for four years after the retirement of Mary Sweeney in January 1964.

The files in the fourth subseries reflect the Director's duties as head of the educational and service staff at the Institute and as the Corporation's representative in dealings with the Spanish government and the educational community in Madrid. The files also show the Director's participation in the selection of staff and scholarship recipients and her/his responsibility for the maintenance of IIGS building(s).

The subseries is divided into six sections: Clerk, Corresponding Secretary, President, Representative in Spain, Treasurer, and General. The section "Representative in Spain" contains correspondence with Enriqueta Martin who acted on the Corporation's behalf in Spain during World War II while Institute activities were curtailed. Mary Sweeney was the director appointed by the Corporation during this period but she remained in the U.S. and Enriqueta Martin represented the Institute in a semi-official capacity.

The fifth and sixth subseries contain the files of the President and the Treasurer of the Corporation each filed chronologically. The President's files contain letters written of behalf of the Corporation and the Treasurer's files are principally about Institute and Corporation finances.

The seventh subseries, General, is divided into four sections. The first, 'Miscellaneous' consists of correspondence of staff members and Corporators of the IIGS who are not in one of the six major positions in the first five subseries. The second section, 'Ilene Avery', consists of personal correspondence of one of the Institute's directors which reflects her involvement in the educational community in the U.S. and Spain, but is not directly related to Institute business. The third section is the correspondence of 'Enriqueta Martin', long-time librarian of the Institute and director of the Library Science Program. Her correspondence has been separated from the bulk of the general correspondence because of her long service and intense involvement with the Institute. The fourth section is the correspondence of 'Mary Sweeney' from the period immediately following her retirement as Corresponding Secretary on January 1, 1964. This correspondence has been isolated because she continued to perform many of the duties of the Corresponding Secretary while not actually holding the post.

Correspondence in each of these sections is arranged chronologically.

The records in this series consist of accounts, budget summaries, annual and other forms of financial reports, and topical files on building, donations, rents, salaries, and tuition. None are complete. Some of the records were maintained in Spain by IIGS staff and others by the Treasurer in the United States and are so identified on the folder title list where possible.

In addition to covering daily operating expenses and annual budgets, the records also contain some information about policies and the IIGS financial relationship with Estudio.

Related material may be found in the Treasurer's Correspondence - Series II and in the Minutes - Series VIII.

The records are arranged alphabetically by type and then chronologically within each type.
