This chapter examines collective collecting as a central feature of the do-it-yourself (DIY) practice of archiving affectively. It focuses on the research undertaken for the Australian Research Council-funded projects "Popular Music and Cultural Memory" and "Do-It-Yourself Popular Music Archives". That affective practice can be communal is essential to an understanding of the potentialities of affective archiving in the preservation of popular music's material culture. In many community archives, the project of archiving can be understood to have begun because of feelings of love and care related to the custodianship of popular music's heritage, rather than because of an abstract concept related to saving material for the national interest. On affect, the DIY archives and museums can be thought of "as places in which affect is produced and made possible through community and the process of remembering, and made again through encounters with objects that inspire both these things".
