How do recuperative historiographies of sexuality mobilize salutary forms of loss in the service of collectivities tallying up what they do not as yet have in relation to other constituencies? Far from repudiating such salvific historical forms (instantiated as they routinely are in the language of lost rights and representation), the introduction asks (1) how minoritized conclaves wrestle with the evidentiary genres that such models of devaluation demand, and (2) how they assemble historical archives that self-consciously activate the compensatory mechanisms that such losses should or will produce. The challenge here is to engage a historiography of sexuality that paradoxically adds value to a sedimented historical form (lost archives must be resurrected, found, produced for future gains) precisely by staging interest in its modes of reproduction (found archives must be disseminated, digitalized, and memorialized). To speak of a history of sexuality from the Ansatzpunkt of abundance is to emphasize both the efflorescence of the past, and to attend to its strategic and active mobilization within the politics of the present.
