The two earliest manuscripts (hand-written copies) of "The Canterbury Tales" are the Hengwrt manuscript and the Ellesmere manuscript. There are also 84 manuscript and four printed copies of "The Canterbury Tales" that were made before 1500. There are quite a lot of differences in the different copies. Some experts on Chaucer have started The "Canterbury Tales Project". The project is to read all these copies of "The Canterbury Tales", find out the differences and write the most accurate copy.
