This collection reflects on the emerging phenomenon of 'selfie citizenship', which capitalises on individual visibility and agency, at the time when citizenship itself is increasingly governed through biometrics and large-scale dataisation. Today we are witnessing a global rise of politicised selfies: photographs of individuals with handwritten notes or banners, various selfie memes and hashtag actions, spread on social media in actions of protest or social mobilistion. Contributions in this collection range from discussions of citizen engagement, to political campaigning, to selfies as forms of citizen witnessing, to selfies without a face. The chapters cover uses of selfies by activists, tourists and politicians, victims and survivors, adults and children, in a broad range of geopolitical locations -China, Germany, Iran, Nepal, Pakistan, Singapore, South Korea, Sweden, the UK and the US. Written by an international and interdisciplinary group of authors, from senior professors to junior scholars, artists, graduate students and activist, the book is aimed at students, researchers, and media practitioners.
