International Dunhuang Programme, British Library, Diamond Sutra (Or.8210/P.2)

International Dunhuang Programme, British Library, Diamond Sutra (Or.8210/P.2), the British Library's own digitization record for its copy of the world's earliest complete dated printed book, is a primary institutional catalogue and imaging record from the library that physically holds the scroll. Its strength is direct custodial authority: the most reliable available source for the manuscript's shelfmark, physical description and digitized images. Its limit is that a catalogue and digitization record establishes custody and physical description, not a scholarly study of the sutra's textual content or its place in the history of printing, which should be sought in dedicated scholarship; no named author or publication year is given here because a live institutional catalogue record of this kind is properly cited by shelfmark and repository rather than as a dated publication.
