Although it began as the personal library of one of the most influential art historians and connoisseurs of the last century, the Biblioteca Berenson now has a broad interdisciplinary scope that goes far beyond art and art history. As the library of Harvard University’s Center for Italian Renaissance Studies since the 1960s, it has become a major resource for research into all aspects of the society, culture and thought of Italy between about 1200 and 1650. Nonetheless the Berenson Library offers rich and often unique resources for art historical research, both on the Renaissance and on the 20th century.
