Dispute Over Bill on Borrowed Art.

The lending and borrowing of famous artworks is the essence of cultural exchange between museums in the United States and abroad. So routine is the practice, and so universally valued, that the American government has traditionally protected it with a law that shields a lent work from being seized by anyone with a claim to legal ownership while the art is on display here. In recent years, though, American museum directors have come to fear that this safeguard has eroded, and that foreign museums, dreading entanglement in costly ownership battles, are more hesitant to make loans. So they have asked Congress to increase the security for global art swaps. [ABSTRACT FROM AUTHOR]
