SUMMARY OF DIRECT CHARITABLE ACTIVITIES FORM 990-PF, PART IX-A, LINES 1 & 2 ARCHIVAL PROGRAM (CONTINUED):THE ARCHIVE CENTER IS LOCATED IN HILLCREST, A HOME OF WESTCHESTER COUNTY FIELD STONE BUILT FOR MARTHA BAIRD ROCKEFELLER (1895-1971), THE SECOND WIFE OF JOHN D. ROCKEFELLER, JR. (1874-1960). THE HOUSE WAS DESIGNED BY MOTT B. SCHMIDT AND WAS COMPLETED IN 1963. MRS. ROCKEFELLER PERSONALLY PLANNED THE FURNISHINGS OF THE HOUSE, BUT ADVANCING AGE AND ILLNESS PREVENTED HER FROM LIVING IN IT. AFTER HER DEATH, THE HOUSE WAS GIVEN TO THE ROCKEFELLER BROTHERS FUND AS PART OF HER RESIDUAL ESTATE. IN MARCH 1974 THE ROCKEFELLER BROTHERS FUND GAVE THE HOUSE AND THE SURROUNDING 24 ACRES OF GROUNDS FOR USE AS THE ROCKEFELLER ARCHIVE CENTER.THE HOUSE PROVIDES WORK SPACE FOR BOTH RESEARCHERS AND STAFF AND INCLUDES A FEW ROOMS WHERE ROCKEFELLER MEMORABILIA ARE ON DISPLAY. RESEARCHERS WHO VISIT THE RAC WORK IN THE READING ROOM ON THE SECOND FLOOR OF THE HOUSE AND MAY USE THE RESEARCHERS' LOUNGE ON THE FIRST FLOOR.THE CENTER'S READING ROOM IS OPEN TO RESEARCHERS ON WEEKDAYS FROM 9:00AM UNTIL 5:15PM. RESEARCH APPOINTMENTS ARE REQUIRED. APPOINTMENTS MUST BE MADE WITH, AND CONFIRMED BY, A STAFF MEMBER IN ADVANCE OF A RESEARCH VISIT. PHOTO IDENTIFICATION IS REQUIRED.

THE STAFF WILL RESPOND WITH A DESCRIPTION OF THE SCOPE AND CONTENT OF RELEVANT MATERIALS IN THE COLLECTIONS.RESEARCH & EDUCATION (CONTINUED):THE EDUCATIONAL PROGRAMS ENGAGE A NUMBER OF AREA COLLEGES AND UNIVERSITIES. THE RAC BRINGS UNIVERSITY FACULTY AND THEIR GRADUATE OR UNDERGRADUATE STUDENTS TO THE ARCHIVE CENTER FOR COURSE-RELATED LECTURES AND SEMINARS, ADVISES STUDENTS ON PAPERS AND THESES, AND HELPS FACULTY TO FIND PRIMARY MATERIALS FOR THEIR TEACHING. THE STAFF ALSO PARTICIPATES IN MEETINGS OF VARIOUS PROFESSIONAL ASSOCIATIONS, DELIVERING PAPERS AND ORGANIZING PANELS FOR RAC RESEARCHERS. A NEW EDUCATIONAL PROGRAM HAS BEEN DEVELOPED IN COLLABORATION WITH TWO ELEMENTARY SCHOOLS IN TARRYTOWN AND POCANTICO HILLS. ITS AIM IS TO TEACH YOUNG STUDENTS ABOUT THE USE OF PRIMARY SOURCES IN THEIR HISTORY CLASSES.THERE ARE SEVERAL PUBLIC OUTREACH INITIATIVES OF THE RESEARCH AND EDUCATION PROGRAM. THE RAC OCCASIONALLY INVITES MEMBERS OF LOCAL HISTORICAL SOCIETIES TO TOUR THE ARCHIVES.
