with the plantings brushing the glass walls and the sound of splashing water audible in the central fountain. To further this idea, he incorporated four interior glazed planter areas situated between the galleries and the fountain. Johnson also believed that the pavilion was to be best enjoyed from the inside. In addition to offering interesting garden views, the eight gallery spaces allow for a well-organized circulation plan. They also provide intimate areas for visitors to enjoy and study the Pre-Columbian objects. Each interconnected exhibition gallery is twenty-five feet in diameter, having curved glass walls supported by cylindrical columns sheathed in Illinois Agatan marble and shallow domes that rise from flat bronze rings. The floors are teak, laid radially and ended by wide rims of mottled green Vermont marble. Library The Dumbarton Oaks Research Library contains more than 200,000 items that support the three studies programs. The Byzantine holdings of materials concerning late classical, early Christian, Byzantine, and medieval art and archaeology, which numbered 8,000 volumes at the time of the Blisses’ gift, now number 149,000 volumes with more than 550 journal subscriptions. In 1964, the Research Library acquired Robert Woods Bliss's personal collection of 2,000 rare and important works on Pre-Columbian art history, anthropology, and archaeology, which has since grown to more than 32,000 volumes, and Mildred Bliss's garden library, including rare volumes and prints, which now includes 27,000 books and pamphlets. The Rare Book Collection has holdings of more than 10,000 volumes, prints, drawings, photographs, and blueprints. The Rare Book Room, designed by Frederick Rhinelander King in the style of an 18th-century library, was completed in 1963 to house the collection of rare books and drawings which had been started by Mildred Bliss. Her library was enlarged, with advice from Beatrix Farrand, designer of the Dumbarton Oaks garden, once Mrs. Bliss conceived the idea in the 1950s of starting a program of studies in landscape architecture. The Research Library is housed separately from the Rare Book Collection, in a building designed by VSBA architects and completed in 2005. The collection of books originated in Mrs. Bliss's aim to preserve illustrated books from being broken up for individual plates. There are volumes of views which are especially valuable for the study of gardens since few of the sites survive as originally created. For example, Giovanni Battista Falda’s 17th-century plates showing the gardens of Rome; views of Versailles and other royal
