A Personal Lifelog (PL) archive gathers together digitally captured data taken from the real life events of an individual. These can include for examples details of computing activities and capture of other digital artefacts such as photos. Personal information management (PIM) research is focused on making use of personal digital content. We believe that findings from studies of personal episodic memory can be used to assist the development of search tools for PLs. We exploit the temporal associations among the PL items, and present an interface for search of personal archives. This displays personal landmarks on a timeline, including items such as captured digital photos and keywords from information accessed on computing devices during corresponding periods. This enables users to search and browse their PL archives based on recall of significant events or items, rather than needing to remember explicit temporal features such as date and time.
