“Basic human things”: Investigating vehicle residents' continually fractured (information) landscapes

Journal of the Association for Information Science and Technology, Volume 77, Issue 3, Page 503-520, March 2026.
Abstract This ethnographic study explores vehicle residents' information practices in the United States (US). Vehicle residents are people whose primary means of housing is a vehicle. This work builds on previous research encompassing transitions and fractured (information) landscapes. Using fractured information landscapes as the theoretical framework,
