On April 14, Secretary of State Powell issued this press release, Cooperation for the Safeguarding of Iraqi Antiquities and Cultural Property. See my related postings on the recent lootings of the Iraqi National Museum and libraries.
For reference, from the State Deparment website, see U.S. Laws and International Laws which address “the looting and destruction of archaeological sites and the theft of cultural property,” as well as this recently launched website, Iraqi Cultural Heritage in Peril, which links to selected images of looted items. For additional information, see UNESCO’s more extensive topical resource, as well as this site, Lost Treasures from Iraq, from the Oriental Institute, University of Chicago, which has posted numerous images of artifacts, as well as a Bibliography of books documenting the contents of the Iraq Museum, et al.
