Major museum acquisitions are often hailed as “transformative”, and this rang especially true for several institutions in 2018. Donations of more than 1,300 works apiece will turn the Institut du Monde Arabe in Paris and Vienna’s Albertina into centres for contemporary art. The Albertina and the University of Texas are creating new spaces to house collectors’ gifts, while almost 11,000 works from the defunct Corcoran Art Gallery in Washington, DC, have found permanent new homes. And the Baltimore Museum of Art controversially used deaccessioning as a force for change, putting the proceeds from the sale of blue-chip works towards more diverse purchases. Here, we look back at some of the most significant acquisitions of the year.
