"* The PCF -The Public Catalogue Fondation - was launched in 2003. It is a registered charity and is based in London. It has a network of researchers and photographers working across the country from the Channel Islands to Northern Ireland."
"The PCF* (through the Your Paintings website) is asking the public to help it catalogue (or ‘tag’) paintings by subject matter online via the Your Paintings Tagger.
By looking at the paintings in detail, 'taggers’ are be able to help generate useful subject classifications for each work and supply important keyword information including information about people, places and events shown in the painting."
PCF : "Your Paintings Tagger is a unique project that is helping search online our entire national collection of oil paintings – some 200,000 works in total..."
