Practices of digitizing cultural assets, especially immaterial ones, are in a certain tension with the objects to which they are dedicated. They bring contemporary interests to bear on the collections and are fed by specific logics of collecting. The contributions in this volume look at exemplary strategies in the process of collecting, indexing and presenting. The particular focus here is on holdings that are precarious for a variety of reasons and require special approaches. The introductory articles are therefore devoted to strategies for collecting and organizing. The middle section focuses on cataloging and indexing, while the concluding contributions are dedicated to practices of digital storytelling and mediation.
