Data Journalism Handbooks

The Data Journalism Handbook 2

Towards a Critical Data Practice

What is data journalism? What is it for? What might it do? What opportunities and limitations does it present? Who and what is involved in making and making sense of it?

The new edition of the Data Journalism Handbook explores new and innovative ways in which data is analysed, created and used in the context of journalism. And beyond that: it also reflects on the social, cultural, political and economic circumstances in which data journalism is embedded.

The Data Journalism Handbook 1

How Journalists Can Use Data to Improve the News

When you combine the sheer scale and range of digital information now available with a journalist’s "nose for news" and her ability to tell a compelling story, a new world of possibility opens up. Explore the potential, limits, and applied uses of this new and fascinating field.

This valuable handbook has attracted scores of contributors since the European Journalism Centre and the Open Knowledge Foundation launched the project at MozFest 2011. Through a collection of tips and techniques from leading journalists, professors, software developers, and data analysts, you’ll learn how data can be either the source of data journalism or a tool with which the story is told—or both.
