Great news! The Vatican Library has digitised Codex Vaticanus (also known by the siglum ‘B’). Vaticanus is one of the most important biblical manuscripts. It is an uncial manuscript that dates to the mid-fourth century and contains almost the entire Christian canon in Greek, including most of the Apocrypha.
The high quality digitised images of the whole codex can be found at the following URL:
This is a great resource for study of biblical texts. The Vatican Library and the University of Heidelberg, which also contributed to the project, are to be congratulated for bringing this project to fruition and making the resource freely available.
