The Question of Forgeries [http://idp.bl.uk/pages/collections.a4d]
There is little doubt that there are forgeries among the Dunhuang and Central Asian collections although there is little objective proof yet as to their extent. The problem was first made public by Professor Fujieda Akira following his comparison of the Japanese and British collections. In 1998 IDP organised a conference at the British Library to discuss this issue and the papers from the conference were published in 2002.
