“At a news conference this week, the British Museum’s head of treasure, Roger Bland, called on eBay to agree quickly to ‘pull down’ Web auctions of artifacts when British authorities identify them as potential national treasures, a step that eBay has been reluctant to undertake without legal proof that the items qualify as treasure… In negotiations that have stretched over a year, eBay has agreed in principle that it doesn’t want illicit antiquities on its Web site and is willing to remove them provided the British authorities can state clearly which ones are illegal. But British officials have not been able to give a clear definition.”
