The International Dunhuang Project is an enormous online undertaking, with collaboration between more than a dozen institutions committed to making important artifacts and documents about the heritage of the Silk Road available to all. For those visitors unfamiliar with the exact location of the Silk Road, a map can be found in the right hand corner of the "About IDP" link. The vast quantities of material from the Silk Road are located in collections and are scattered around the world due to archeological expeditions from different countries, beginning in the 19th century. The "Collections" link consists of British, Chinese, French, German, Japanese, and Russian collections, as well as other smaller collections, such as in Sweden and Finland, under "Other Collections". Visitors interested in teaching about the Silk Road will find that the "Education" link has a "Teach" section that offers lots of wonderful exercises for those who "wish to explore the culture, languages, religions and creativity of the Silk Road." Some of the lessons include "Cultural Dialogue on the Silk Road: A Mini Gallery" and "Medicine on the Silk Road".
