Distributed Proofreaders provides a web-based method to proofread a Public Domain book to help ease it’s conversion into an e-book. By dividing the workload into individual pages, many volunteers work on a book at the same time.
If you choose to participate in this action, you will be presented with a scanned page image from a public domain book, alongside its corresponding OCR (optical character recognition) text. This allows the text to be easily compared to the image, proofread, and sent back to the site. Proofread as many pages as you want, and when you want. Many books and categories to choose from.
