In 1986 Derrida became Professor of the Humanities at the University of California, Irvine, where he taught until shortly before his death in 2004. His papers were filed in the university archives. After Derrida's death, his widow and sons said they wanted copies of UCI's archives shared with the Institute of Contemporary Publishing Archives in France. The university had sued in an attempt to get manuscripts and correspondence from Derrida's widow and children that it believed the philosopher had promised to UC Irvine's collection, although it dropped the suit in 2007.
