The History of Humanities Computing available online!
The hefty, interesting, and useful "A Companion to Digital Humanities" has been published online at: http://www.digitalhumanities.org/companion/. This is a great and informative book, and the online publishing is great because not everyone can afford it's hefty $160 price tag. It will be released in paperback soon, though, so maybe I'll be able to afford a copy for myself.
