This is geektabulous. The Aleppo Codex, aka the 10th c. manuscript of the Bible considered to be the most authoratative in terms of transmission of tradition (vowels, word choice/spelling Torah trope, etc.) is now online. Much of the original Codex has been lost, but the Ben-Zvi Institute in Jerusalem has now put all (I think) of what remains–the end of Deuteronomy onwards–online. Not only that, but it’s got all sorts of nifty zooming functions, so you can see the manuscript up close and personal. It’s pretty groovy.
Here’s the main Codex site for all sorts of background, or you can jump straight to the nifty zoomable codex itself
