Book excerpt: There is a growing awareness around the world of the pressing need to archive the material remnants of popular music so as to safeguard the national and local histories of this cultural form. Current research suggests that in the past 20 or so years there has been an expansion of DIY heritage practice, with the founding of numerous DIY popular music institutions, archives and museums around the world. This edited collection seeks to explore the role of DIY or Pro-Am (Professional-Amateur) practitioners of popular music archiving and preservation. It looks critically at ideas around "DIY preservationism," "self-authorised" and "unauthorised" heritage practice and the "DIY institution," while also unpacking the potentialities of bottom-up, community-based interventions into the archiving and preservation of popular music’s material history. With an international scope and an interdisciplinary approach, this is an important reference for scholars of popular music, heritage studies and cultural studies.
