If you’re really interested in Islamic law and the law of the Muslim world, check out the Social Science Research Network forthcoming article database on the subject. Plus you can subscribe to the abstract distribution service, I believe for free. (My understanding is that the SSRN makes money from universities that pay for the right to post their faculty papers to various SSRN series, and not from readers.)
I’ve just printed out the Political Liberalism, Islamic Family Law and Family Law Pluralism: Lessons from New York on Family Law Arbitration paper and the Honor Killings and Cultural Defense (with a Special Focus on Germany) paper, and look forward to reading them.
