blindcynic- Like I stated in my blog, the first copy was found in a cave near  Dunhuang in China located close to the trade route known as the silk road. It was hidden in this cave with hundreds of other Buddhist manuscripts in the early 1000's and rediscovered in the early 20th century. 

Lara- The Chinese started using block printing during the early Tang era (618-906), The Diamond Sutra was dated during the dynasties later years. Although I don't know the actual first book to be produced using this method, it is certain others came before The Diamond Sutra. 

Jmpham- I don't know any by name but certainly there are more out there. In fact when The Diamond Sutra was discovered in the cave in 1907 it was found with hundreds of other Buddhist text which i'm assuming were probably most done in block printing as well, if from the same era. There is a block printing museum in China as well called China Block Printing Museum and Yangzhou Museum. The Diamond Sutra however, is located in The British Museum.
