In 1963 Radcliffe gave joint Harvard-Radcliffe diplomas to undergraduates. A formal "non-merger merger" agreement with Harvard was signed in 1977. Radcliffe was fully integrated with Harvard by 1999. Today, in Harvard University, Radcliffe's former campus is now the Radcliffe Institute for Advanced Study. The former Radcliffe housing at the Radcliffe Quadrangle is now in the Harvard College housing system. Under the terms of the 1999 agreement, the Radcliffe Yard and the Radcliffe Quadrangle will always keep the "Radcliffe" name.
