The category of “informal archives” was initially proposed by Adam Auerbach in a case study on the role of informal archives held by social leaders of peripheral communities in India. “Informal archives” imply forms of historical documentation beyond state authority, and preserved in a rough, poor, and ephemeral manner (in the digital realm). They typically involve connections to the past articulated by different social demands, whether regarding the dispute for a national memory in the digital-public realm, or the nostalgic nature of certain connections to the past, or even the social/political activism of civil society organizations. For this reason, informal archives are in unmapped locations, and in order to be accessed they need to be ethnographically reached. An empirical research based on data raised in early 2020 shows that, even with the creation of a theoretical basis for this kind of digital resource, constant updates will remain necessary due to the unstable nature of the subject.
