#I took a class on Islamic Architecture in college and it was fascinating but also easily the hardest architectural history class I had

One fun detail in the illustrations is the Tughra in the library!

Another architectural side quest here but the Tughra is basically the signature of the Sultan, like an official seal to show that it's his building. You would see it on all sorts of things in Istanbul, and it's very neat that Keith Thompson included it in this illustration. Just some lovely attention to detail.
