# Archive sector data we manage

Through our data platform, Discovery, we provide a single point of online access
to catalogue and organisational data from across the archive sector.

Discovery includes:

* the National Register of Archives (NRA)
* Access to Archives (A2A)
* [Find an Archive](https://discovery.nationalarchives.gov.uk/find-an-archive) (formerly ARCHON) directory
* the [Manorial Documents Register](https://discovery.nationalarchives.gov.uk/manor-search)
* [Manage Your Collections tool](https://www.nationalarchives.gov.uk/professional-guidance-and-services/archive-sector/archive-sector-data-we-manage/manage-your-collections/)

* ## [Manage Your Collections in Discovery](https://www.nationalarchives.gov.uk/professional-guidance-and-services/archive-sector/archive-sector-data-we-manage/manage-your-collections/)

  The Manage Your Collections application allows archives to edit information
  about their own collections in The National Archives' online catalogue,
  Discovery.
