This project started in 1971. In those days, books were re-typed into computers. Optical Character Recognition (OCR) software helped to automatically recognise printed text. This method caused errors and correcting them was a difficult task. Distributed Proofreaders [PGDP] – http://www.pgdp.net/ – is an official part of PG. It trains volunteers online and gets the book proofread by many persons till it is finished. This way another book is added to the online public domain, free to anyone. PG now has as many as 33,000 proofread books online. It is an open access archive of digital eBooks and no different to a Free Public Library.
