The Data Journalism Handbook: 
This collaborative book coordinated by the European Journalism Centre and the Open Knowledge Foundation aims to answer questions like: Where can I find data? How can I request data? What tools can I use? How can I find stories in data? How can I make data journalism sustainable? It had a very successful start at the Mozilla Festival in London in November 2011 with fifty contributors, including data journalists and professors from the New York Times, Financial Times, Guardian, Chicago Tribune, Medill School of Journalism, and Cronkite School of Journalism. Additional contributors now include leading developers, analysts, FOI experts, and other practitioners from places like the BBC, City University London, Scraperwiki, Zeit Online, and many others. The project has received coverage in the New York Times, Liberation, Tech Crunch, World Editors Forum, and other major publications.
