Building a museum's permanent collection is an art unto itself.
"It's not like going to Macy's," said Matthew Welch, deputy director and chief curator at the Minneapolis Institute of Art, who has seen many artworks come and go in his nearly 30 years there.
Why do museums collect? By preserving art, they help us understand our world, ensuring that cultural legacies live on.
The very mission of a museum is existential: It's a reminder of our own mortality, and of civilizations that have come and gone — such as the "Egypt's Sunken Cities" show now at Mia — but at the same time it reflects our collective past through a multifaceted contemporary lens.
As Welch put it: "We collect the art of our time, but also respond to the interests of our time."
Historically, art museums were launched by wealthy patrons such as railroad magnate James J. Hill, whose collection of European paintings became a cornerstone for Mia. Gifts make up 92 percent of the museum's collection, which numbers 93,000 objects, the biggest by far among Minnesota art institutions.
Walker Art Center in Minneapolis has more than 11,500, the University of Minnesota's Weisman Art Museum has 25,000 and the Minnesota Museum of American Art in St. Paul just over 5,000.
That is a lot of stuff, and only 2 to 5 percent of it is on public view — much like a public library, but without the checkout privileges (although U of M students can borrow certain works from the Weisman).
