Post-custodialism, distributed custody, and big data

This reflection piece describes the outcomes of a research project undertaken by the National Archives of Australia that aimed to gather information from other government archives and selected Australian government agencies about their approach to archiving and preserving large-big datasets in the government sector. Big data collections pose a challenge for government archives around the world. Many of these archives have a role in information management in their government domains and provide guidance and advice to their government agency clients on ensuring the integrity and trustworthiness of data over time. The article examines the nexus between theory and practice, exploring issues related to the post-custodial ideas developed by Terry Cook and others in the 1990s and their practical implementation.
