The University of Michigan Graduate School has a project on the web called Building Islam in Detroit: An Interdisciplinary Study of Muslim Institutions & Collective Spaces. The site is not fully developed yet, but it sounds like a great project, with case studies planned for a number of masajid around town including Muath bin Jabal near Hamtramck. They have a list of masajid around town, plotted on a map. I’m fond of telling people that Detroit has as many masajid as Kuching; now I have proof. The most fleshed out part of the site is the section that has photographs of various mosques, taken by a photographer visiting from Sudan. Well worth a look.
