Elements in the Global Middle Ages is a series of concise studies that introduce researchers and instructors to an uncentered, interconnected world, c. 500-1500 CE.   Individual Elements focus on the globe’s geographic zones, its natural and built environments, its cultures, societies, arts, technologies, peoples, ecosystems, and lifeworlds.

Born digital, with print-on-demand, and updatable annually by authors, this multidisciplinary Cambridge series of studies takes advantage of the latest digital technology, and is able to embed audio, video, and visual materials.
