The Louisiana Endowment for the Humanities has added a new feature to its expanding digital encyclopedia of Louisiana history and culture -- KnowLA. The LEH is distributing downloadable QR codes to museums statewide. The barcode can be printed and mounted alongside artwork. By scanning it with a smartphone, it takes the viewer from the static piece of art into the rich, interconnected encyclopedia entry. LEH president Michael Sartisky said there are 276 artist entries in KnowLA -- all of them with QR codes – from folk artist Clementine Hunter to Shreveport illustrator Bill Joyce.
