In 2017 AKDC@MIT received over 18,000 slides taken by John A. and Caroline Williams, author of Islamic Monuments in Cairo: The Practical Guide. The images in the collection document sites in Egypt and across the Islamic world over multiple decades. Currently a sampling of about 700 are available online, with more are coming soon. Of course the entire collection is available the Aga Khan Documentation Center for consultation, research, or use in publications.
