Dig no that page is just an ordinary XF Page which I tried to make into a temporary index page for my Libraries. Disregard it.
This one is more representative

That is a single Library, with a single Article in it.
Jon is putting up some screenshots based on a vanilla XF install any minute. He mentioned it earlier today. That is a plain install without my template designs.
It's not being called an Articles Library because it is going to be designed to handle a whole lot more than just Articles, although that is the standard type of item.
