The citations this atlas's facts are drawn from: Encyclopaedia Britannica, Banister Fletcher's history of architecture, Vitruvius's Ten Books in the Morgan translation, UNESCO's World Heritage inscriptions, the Council on Tall Buildings and Urban Habitat's records for anything tall, the Pritzker Prize's own laureate pages, and the official pages of bodies such as RIBA, AIA, the Frank Lloyd Wright Foundation, the Bauhaus Dessau Foundation and the Sagrada Familia. Every specific claim in this atlas is expected to carry a source that actually states it, per this atlas's own write time discipline; a source entity is the record of where that support came from, carrying its own locator and, where captured, a short verbatim supporting quotation.
