n many academic disciplines and professional practices — architecture, urban studies, labor history, development economics, and the information sciences, just to name a few — maintenance has taken on new resonance as a theoretical framework, an ethos, a methodology, and a political cause. This is an exciting area of inquiry precisely because the lines between scholarship and practice are blurred. To study maintenance is itself an act of maintenance. To fill in the gaps in this literature, to draw connections among different disciplines, is an act of repair or, simply, of taking care — connecting threads, mending holes, amplifying quiet voices.
