Embroidered referencing in the New Bodleian

What was the New Bodleian has been turned into the Weston Library with exhibition space and a cafe.To mark the 800th anniversary of the Magna Carta, someone decided to embroider the whole Wikipedia page on the subject. It's huge. What I love about Wikipedia is the way that it is well-referenced. I have been trying to teach my classes to include (date accessed) when referencing web pages. This is important because unlike printed material, they can change.
