The book, through Powells (apparently it's cheaper on Amazon though...).

He has his own page

The January 1, 2006 Sunday New York Times Magazine featured an article by Appiah taken from the book. (by subscription only)

He has also been on the radio a lot:

"Talk of the Nation"

Minnesota Public Radio's "Midmorning" program. (hour 2; see also relevant links to Appiah's other work)

Dara pointed me toward this review in The Nation

Trained as a philosopher with research in moral and political philosophy, Appiah has also published widely in African and African-American studies and in Cultural Studies. His Cosmopolitanism can be seen as a more extended meditation of some issues in his 2004 Ethics of Identity.

I envision 1-2 hours of conversation about Appiah's ideas as well as their relationship to our current work and our disciplines. This would allow us to digest the book and get a sense of its scope and relevance beyond our regular lenses. If you want to join us, do reply directly to me so I can begin coordinating a meeting time.
