The Million Book Project aims to digitize one million public domain books by 2007 through scanning centers located around the world. The project is led by Carnegie Mellon University and has digitized over 1.4 million books as of now through 22 scanning centers in India and 18 in China. Some of the main technical challenges for the project include intellectual property issues, machine translation, metadata handling, information storage, search capabilities, and optical character recognition for non-Roman scripts.
