The Data Rescue Project started in February 2025 as a coordinated effort of three data organizations, including members of IASSIST, RDAP, and the Data Curation Network.

Our goal is to serve as a clearinghouse for data rescue-related efforts and data access points for public US governmental data that are currently at risk. We want to know what is happening in the community so that we can coordinate focus. Efforts include: data gathering, data curation and cleaning, data cataloging, and providing sustained access and distribution of data assets.
