The Wall Street Journal chats with Maya Lin, the collector.  Turns out Lin is the kind of collector who needs serious storage space:

Ms. Lin tends to keep her collections well away from public view. She values privacy. She also prefers uncluttered spaces. Indeed, she and her husband, Daniel Wolf — an art dealer and film producer — have locked away the bulk of their possessions in a warehouse, opting to store such diverse objects as Scandinavian glass, Chinese ceramics, and contemporary American paintings and photography, along with Ms. Lin’s personal rock collection, which she has been compiling since high school.[…]

Do you trade work with other artists?

I had a group of friends [at Yale University], and afterward we were all in New York and we were always swapping art. It was a pretty interesting group of artists: Lisa Yuskavage, Richard Phillips, Carl Ostendarp, Sean Landers, John Currin and Beverly Semmes, among many others.
