Extra resources
Hi Chelsea,
Your wiki entry is so well-researched that I don't have a lot more to suggest. However, if you want more info on the whole cultural nationalism vs. internationalism issue, here are a couple of resources: World Heritage List: Bridging the Cultural Property Nationalism-Internationalism Divide, The Notes by Anglin, Raechel http://heinonline.org/HOL/Page?handle=hein.journals/yallh20&collection=journals&page=241
and Why Do Think Its Yours - An Exposition of the Jurisprudence Underlying the Debate between Cultural Nationalism and Cultural Internationalism by Sljvic, Ana http://heinonline.org/HOL/Page?handle=hein.journals/gwilr31&collection=journals&page=393.
