Over two days, 55 contributors wrote 60 pages of a step-by-step handbook to data journalism. Led by Liliana Bounegru of the European Journalism Centre and Jonathan Gray from the Open Knowledge Foundation, the collaboratively written handbook covers lessons for obtaining, cleaning, analyzing, annotating, and distributing data. It talks about the larger impact of data journalism and essential skills for understanding and getting involved this emerging field. The first draft is available online and a more expanded and polished version is coming soon. You can follow the project with the hashtag #ddjbook or join the data journalism mailing list. Learn more.
