You can read it at no cost online, because the University of Michigan Press has a digital publishing initiative based on giving stuff away. Course you can buy the book too, and keep the age of print going a while longer.
Blurb about the book here. Full text here. And this is a note about it by Jonathan Jarrett, medievalist blogger extraordinaire at Corner of Tenth Century Europe, who graces the collection with an essay on history blogging and other forms of the "informal" digital practice of history.
Topics include the wisdom of crowds, teaching digitally (and teaching Wikipedia "without apologies,") "reflections on 10,000 digital notecards," working with "needles in a data haystack," using digital for visual, spatial, and game-playing history, public history online, collaborative writing in the social media moment, and much else.
