The Chinese Text Project is an online open-access digital library that makes pre-modern Chinese texts available to readers and researchers all around the world. The site attempts to make use of the digital medium to explore new ways of interacting with these texts that are not possible in print. With over twenty thousand titles and more than three billion characters, the Chinese Text Project is also one of the largest databases of pre-modern Chinese texts in existence.
