There are qualitative data collections (usually in paper form) residing in Special Collections archives, regional archives and museums across the UK. The UK Data Service and its predecessors – including Qualidata, the first dedicated national data service for qualitative data – have helped many European and international data archives archives in their efforts to ingest, curate, and share qualitative data. We have also helped provide start-up advice for many archiving organisations in their efforts to bring in qualitative data.
