1,124,759 in 2020. However, in 2021, the museum attracted 1,958,000 visitors, ranking fourth on the list of most-visited art museums in the world. Other services such as the research libraries were almost completely closed except for off-site digital access. As a result, 20 percent of staff positions were eliminated, and Met director Max Hollein indicated that the Met might deaccession and sell off some of its collection to make up financial shortfalls. At least some of the museum's large art holding was placed in storage in order to make-up for losses in revenue causes by responses to the pandemic. Acquisitions and deaccessioning The Metropolitan Museum of Art spent $39 million to acquire art for the fiscal year ending in June 2012. At the same time, the museum is required to list in its annual report the total cash proceeds from art sales each year and to itemize any deaccessioned objects valued at more than $50,000 each. It must also sell those pieces at auction and provide advance public notice of a work being sold if it has been on view in the last ten years. These rules were imposed by the New York State Attorney General in 1972. During the 1970s, under the directorship of Thomas Hoving, the Met revised its deaccessioning policy. Under the new policy, the Met set its sights on acquiring "world-class" pieces, regularly funding the purchases by selling mid- to high-value items from its collection. Though the Met had always sold duplicate or minor items from its collection to fund the acquisition of new pieces, the Met's new policy was significantly more aggressive and wide-ranging than before, and allowed the deaccessioning of items with higher values which would normally have precluded their sale. The new policy provoked a great deal of criticism (in particular, from The New York Times) but had its intended effect. Many of the items then purchased with funds generated by the more liberal deaccessioning policy are now considered the "stars" of the Met's collection, including Diego Velázquez's c. 1650 Portrait of Juan de Pareja and the Euphronios Krater depicting the death of Sarpedon (which was repatriated to Italy in 2006). In the years since the Met began its new deaccessioning policy, other museums have begun to emulate it with aggressive deaccessioning programs of their own. The Met has continued the policy in recent years, selling such valuable pieces as Edward Steichen's 1904
