The John D. Rockefeller, Jr. Library, nicknamed "the Rock," is the primary teaching and research library for the humanities, social sciences, and fine arts at Brown University in Providence, Rhode Island. It is one of five individual libraries which make up the Brown University Library.
The library was named after John D. Rockefeller Jr., who graduated in the class of 1897. The building was constructed between 1962 and 1964.
The most recent renovations of the "Rock" include the creation of the David and Laura Finn Reading Room (2009), the Patrick Ma Digital Scholarship Lab (2012) and the Main floor reading room (2014).
