The Corpus Vitrearum Medii Aevi of Great Britain [CVMA (GB)] and the National Monuments Record (NMR), the public archive at English Heritage, have contributed approximately 18,000 images of medieval stained glass windows in Great Britain to the Artstor Digital Library, providing a comprehensive and rare archive documenting all aspects of the medium from the period.

Founded in 1949, the CVMA is an international research project dedicated to the publication of medieval stained glass. To date, committees in 14 countries (Austria, Belgium, Canada, Germany, Great Britain, Italy, the Netherlands, Poland, Portugal, Russia, Spain with Catalonia, Switzerland, and the United States of America) have collectively published nearly 100 printed volumes. CVMA (GB), Great Britain’s national survey of medieval stained glass, is a British Academy Research Project hosted by the University of York. In addition to its ongoing efforts to publish all medieval stained glass in Great Britain to 1540, CVMA (GB) has undertaken a project to create a digital Picture Archive, which they have made available on their website.

The majority of these digital images have been provided by the National Monuments Record (English Heritage) in Swindon, which houses the CVMA photographic archive. With partial funding from Artstor and the Arts and Humanities Research Board other sets of images have been digitized.
