Archnet: Archnet is a globally-accessible, intellectual resource focused on architecture, urbanism, environmental and landscape design, visual culture, and conservation issues related to the Muslim world. Archnet’s mission is to provide ready access to unique visual and textual material to facilitate teaching, scholarship, and professional work of high quality. Officially launched in 2002 as a partnership between the Aga Khan Trust for Culture and the Massachusetts Institute of Technology (MIT), Archnet has since evolved into the largest open, online architectural library with a focus on Muslim cultures. Its digital archives form a comprehensive resource on architecture, urban design, landscape, development, and related issues. Archnet provides a bridge for interested persons to learn how to enhance the quality of the built environment, to compensate for lack of resources for students and faculty in academic institutions, and to highlight the culture and traditions of Islam.
