The Artstor Digital Library is a nonprofit resource that provides over 1.6 million digital images in the arts, architecture, humanities, and sciences with an accessible suite of software tools for teaching and research.
A large collection of commonly studied buildings. Includes photos, plans, 3-D walkthroughs, drawings, and a bibliography for each building.
Tip: Be careful when you are using online image search engines like Google Images. Sometimes people don't label their photos correctly. Confirm what your building looks like in a reputable source first!
