As COVID-19 dramatically alters the museum sector, museums and archives are implementing collection initiatives that will have tremendous influence over how the pandemic is understood and remembered. As collections experts, museums are leading the charge to document, collect, and interpret our current circumstances as they unfold in real time, relying more than ever on public participation and crowd-sourcing. A key development in such rapid-response collecting has been the interest in and solicitation of contributions that document the current crisis. Yet, initiatives that target young people remain few and far between, and often reproduce romanticized and reified understandings of children and childhood that reflect a longer history of excluding children’s voices from museum collections and society at large. This paper will explore museums’ collection of children’s culture in various forms with attention to the epistemological and ethical challenges that such initiatives entail. We argue that children are crucial citizens whose knowledge, perspectives, and experiences must be collected and preserved during this historic moment and beyond, in ways that attend to the particular circumstances they face as multiply marginalized museum constituents and members of society.
