What is thought to be the earliest surviving Christian Bible, called the Codex Sinaiticus, has been digitized, according to the Associated Press. The codex is said to be 1,600+ years old and is written in Greek. You can visit the document online at www.codexsinaiticus.org
In the brick and mortar world, parts of the book are located in various locations, including the British Library and Leipzig University Library.
teri, I'm sure that you'll be interested to note that the Codex Sinaiticus includes parts of the Old Testament, Aprocopha, a complete New Testament and a couple of texts not included in any modern canon (Barnabas and Shepherd of Hermas, I believe).
