Digital Witness: Using Open Source Information for Human Rights Investigation, Documentation, and Accountability edited by Sam Dubberley, Alexa Koenig, Daragh Murray (2020), Oxford University Press, Oxford, 384pp., paperback £30, ISBN: 9780198836070

Digital Witness, a new collection edited by Sam Dubberley, Alexa Koenig and Daragh Murray, is a book that defines a field. The potential of user-generated content to document human rights abuses has been recognized since George Holliday filmed the Los Angeles police beating Rodney King – a moment that catalysed the foundation of Witness, a global organization dedicated to empowering communities to document human rights violations. However, it is only within the last decade, with the widespread availability of mobile phones equipped with cameras and internet speeds that allow sharing of digital images, that the potential of user-generated documentation has become a reality.
