I don’t know as much about architecture as I feel I should – it seems like an area I should be interested in, with its balance of design and engineering. It’s not a great site for beginning reading, but the collection of images of buildings at The Great Buildings Collection (some of them 3D models, though you need to download special software to view them) is very extensive and detailed. If I get some projects off my plate I might have to order one of the basic books off the bibliography list.
