This document summarizes a presentation on the role of libraries in data exchange. It discusses several projects by LIBER and the European Research Infrastructure to promote data sharing and preservation. A survey found that libraries need to develop skills and strategies for data citation, curation, and preservation. Moving forward, libraries should advocate for digital preservation policies, invest in workforce training, and help educate researchers on data management best practices. Overall, the presentation argues that libraries have an important role to play in supporting open data and research reproducibility.
