The world's oldest Christian Bible just got digitized.

The pages of what's called the Codex Sinaiticus have been housed in four locations across the globe for more than 150 years.

But now, the fourth-century book, written in Greek, has been digitally reunited in a project involving groups from Britain, Germany, Russia and Egypt, which each possessed parts of the 1,600-year-old manuscript.

The book's digital form was made available to the public this week at www.codexsinaiticus.org. Which is very cool if you're interested in the early spread of Christianity or the advent of book publishing.

This is a major event in the digitization of history. But the Web's teeming with all sorts of digital-archive goodness. Here's a look at some of what you can find.

Highlights of digitized history As with most Web-related things, the number of historical documents online is overwhelming.

So this list of primary document sites is predominantly American and by no means comprehensive. But it is, we hope, a good start.

Library of Congress and The National Archives: Both have an extensive collection of American history, including images, video, audio and more ranging from the country's founding to modern times.

Footnote: A refreshingly different and addictive way of experiencing history. This is a hybrid of original historical documents and social networking that allows users to look through 130,000 images and annotate, label or comment on certain parts of them like one would a Facebook photo. The Flash-powered document viewer allows users to explore the finer details of the images.

- George Eastman House (flickr.com/photos/george_eastman_house/)
