In order to promote the comprehensive use of the Dunhuang Library Cave materials dispersed worldwide, the International Dunhuang Project( IDP) was founded in 1994 to ensure the restoration,cataloguing and conservation of Dunhuang, Turfan and other Chinese Central Asian manuscripts and artefacts.With the development of network technology, IDP hopes to create high quality images of the material and make them freely accessible to everyone online through working together internationally. Over the past decade,IDP Centres have been established in several countries. This paper gives a brief history of IDP in its first two decades and discusses its impact on scholarship of the Library Cave contents.
