Oliver, who published over 30 poetry collections and is a Book Riot favorite, died at home. She also published essays and books on writing poetry. As a young poet from Cleveland, Oliver wrote to the late poet Edna St. Vincent Millay’s sister to ask permission to visit Millay’s home; the request was granted and Oliver spent several years there with Millay’s papers. While living there, she also met photographer Molly Malone Cook; they were a couple for over 40 years, until Cook’s death in 2005.
