How I wish this announcement came in time for Hallowe’en!

The latest institution to benefit from QRpedia is Washington D.C.’s Congressional Cemetery.

Here’s the coverage from a local news channel.

The cemetary is 205 years old and is now the world’s largest outdoor encyclopedia of American history.

You can see photos of some of the codes over on Wikimedia Commons, including J Edgar Hoover, John Philip Sousa and many other distinguished “residents”.

Massive thanks to Peter Ekman for all his hard work and to the staff of the Congressional Cemetary for agreeing to take part in this project.
