The British Library launched its Digitised Manuscripts website on 27 September 2010 with images of 284 Greek manuscripts.
The selected manuscripts are from the Additional and Harley manuscript collections and date from the sixth to the 18th centuries AD. They include literary, historical, biblical, liturgical and scientific texts. The Browse function lists 285 [sic] manuscripts in order of shelf mark.
The Greek Manuscripts Digitisation Project, funded by the Stavros Niarchos Foundation, aims to digitise the medieval and earlier manuscript collections of the British Library. There is a related Medieval and Earlier Manuscripts Blog.
