This paper reflects on an emerging field that has no accepted name or boundaries but is described here as “digital biography.” The activities, formats, and genres associated with this field are rarely linked with life writing or traditional biographical studies. Rather, this field is seen as the domain of those concerned with digital privacy, copyright, data preservation, and identity management. Over the past decade or so, critics in various disciplines, mainly legal studies, information management, multimedia design, and IT development, as well as sociology, psychology, and marketing, have focused on the complexity of online identity. Though online identity has become such a significant focus of attention in these disciplines, few who study biography have discussed it. Indeed, as Nigel Hamilton points out, biography itself has had less attention than one might expect for a field that “has enjoyed an extraordinary renaissance in recent years”, a field that, according to Carl Rollyson, is widely recognized as “the dominant non-fiction of our age”.
