This article presents a short selective history of contemporary collecting at the Smithsonian Institution. I explain what contemporary collecting is and show how contemporary collecting in the 1960s and 1970s produced histories of political reform movements and participatory democracy. I argue that many material records would not exist today if it had not been for a small group of committed curators who pioneered this practice in the absence of policy guardrails—and often despite a lack of institutional support. I present a brief overview of contemporary collecting methods and outcomes to argue that it is more important than ever for us to collect evidence of diverse political activity in our current moment—a moment in which cultural institutions, including the Smithsonian, are being attacked by executive orders issued by President Donald Trump, despite their long-standing reputation for maintaining truth and public trust in times of political change and contestation. The article concludes by suggesting how people can approach this work today.
