[F]rom the very beginnings of informatics—the science of information—as an institutionalized field in the 1960s, anti-capitalists have tried to imagine less oppressive, perhaps even liberatory, ways of indexing and searching information. Two Latin American social movements in particular—Cuban socialism and liberation theology—inspired experiments with different approaches to informatics from the 1960s to the 1980s. Taken together, these two historical moments can help us imagine new ways to organize information that threaten the capitalist status quo—above all, by facilitating the wide circulation of the ideas of the oppressed.
