Great news - the Codex Sinaiticus is going to go online next year:

When the different parts are digitally united next year in a £1m project, anyone will be able to compare and contrast the Codex and the modern Bible.
Firstly, the Codex contains two extra books in the New Testament.
One is the little-known Shepherd of Hermas, written in Rome in the 2nd Century - the other, the Epistle of Barnabas. This goes out of its way to claim that it was the Jews, not the Romans, who killed Jesus, and is full of anti-Semitic kindling ready to be lit. "His blood be upon us," Barnabas has the Jews cry.
The Codex - and other early manuscripts - do not mention the ascension of Jesus into heaven, and omit key references to the Resurrection, which the Archbishop of Canterbury has said is essential for Christian belief.
Other differences concern how Jesus behaved. In one passage of the Codex, Jesus is said to be "angry" as he healed a leper, whereas the modern text records him as healing with "compassion".
Also missing is the story of the woman taken in adultery and about to be stoned - until Jesus rebuked the Pharisees (a Jewish sect), inviting anyone without sin to cast the first stone.
Nor are there words of forgiveness from the cross. Jesus does not say "Father forgive them for they know not what they do".
