"'Your Archives' is a wiki established to allow the public to publish information they have found in archival records to benefit other researchers. This is the first example of an archive enabling the public to add information about ""the nation's memory"" to its website, allowing information sharing on an unprecedented scale.

Responding to the public's growing appetite for online history, 'Your Archives' allows The National Archives to harness the knowledge of its customers and employ this for the benefit of present and future researchers, providing an easy and accessible gateway to this valuable national information."
