Obama Presidential Center, the first digitalised museum to open

The Obama Presidential Center will open to the public on the American federal holiday of Juneteenth, after a celebratory dedication in Chicago with dignitaries. But tens of thousands of people are getting a sneak peek as crews finish final art installations and landscaping.

The roughly 850-million-US-dollar project covers both the political and personal realms of the nation's first Black president. Campaign memorabilia and presidential artifacts are displayed in the admission-based museum tower while public spaces of the sprawling campus feature other things important to Obama - a new library, basketball court and picnic area with grills.

Unlike other presidential museums, Obama's doesn't contain reams of official papers. It's the first fully digitalised presidential museum where unclassified documents can be viewed through a website they are calling a 'digital reading room.'
