National Archives Digital Vault

The National Archives has created the Digital Vault website, which is conceptually fun but not entirely function in my opinion. They've taken they're digital content and tried to create what sort of look like mind maps linking related content together, but the keywords associated with the documents are not terribly accurate, it's a memory intensive site that loads kind of slowly, and the search mechanism isn't so great for getting to something you really need. Still, it's fun to play with and might be a tool to use for students who are looking for 19th century and later primary souces. http://www.digitalvaults.org/
