Distributed Proofreaders (commonly abbreviated as DP or PGDP) is a web-based project that supports the development of e-texts for Project Gutenberg by allowing many people to work together in proofreading drafts of e-texts for errors. As of July 2024,^[update] the site had digitized 48,000 titles.^[2][3][4][5]

History

Distributed Proofreaders was founded by Charles Franks in 2000 as an independent site to assist Project Gutenberg.^[6] Distributed Proofreaders became an official Project Gutenberg site in 2002.

On 8 November 2002, Distributed Proofreaders was slashdotted,^[7][8] and more than 4,000 new members joined in one day, causing an influx of new proofreaders and software developers, which helped to increase the quantity and quality of e-text production. In July 2015, the 30,000th Distributed Proofreaders produced e-text was posted to Project Gutenberg. DP-contributed e-texts comprised more than half of works in Project Gutenberg, as of July 2015^[update].

On 31 July 2006, the Distributed Proofreaders Foundation was formed to provide Distributed Proofreaders with its own legal entity and not-for-profit status. IRS approval of section 501(c)(3) status was granted retroactive to 7 April 2006.

Proofreading process

Public domain works, typically books with expired copyright, are scanned by volunteers, or sourced from digitization projects and the images are run through optical character recognition (OCR) software. Since OCR software is far from perfect, many errors often appear in the resulting text. To correct them, pages are made available to volunteers via the Internet; the original page image and the recognized text appear side by side.^[9] This process thereby distributes the time-consuming error-correction process, akin to distributed computing.

Each page is proofread and formatted several times, and then a post-processor combines the pages and prepares the text for uploading to Project Gutenberg.

Besides custom software created to support the project, DP also runs a forum and a wiki for project coordinators and participants.

DP Europe

In January 2004, Distributed Proofreaders Europe started, hosted by Project Rastko, Serbia.^[10] This site had the ability to process text in Unicode UTF-8 encoding. Books proofread centered on European culture, with a considerable proportion of non-English texts including Hebrew, Arabic, Urdu, and many others. As of October 2013^[update], DP Europe had produced 787 e-texts, the last of these in November 2011.

The original DP is sometimes referred to as "DP International" by members of DP Europe. However, DP servers are located in the United States, and therefore works must be cleared by Project Gutenberg as being in the public domain according to U.S. copyright law before they can be proofread and eventually published at DP.

DP Canada

In December 2007, Distributed Proofreaders Canada launched to support the production of e-books for Project Gutenberg Canada and take advantage of shorter Canadian copyright terms. Although it was established by members of the original Distributed Proofreaders site, it is a separate entity. All its projects are posted to Faded Page, their book archive website. In addition, it supplies books to Project Gutenberg Canada (which launched on Canada Day 2007) and (where copyright laws are compatible) to the original Project Gutenberg.

In addition to preserving Canadiana, DP Canada is notable because it is the first major effort to take advantage of Canada's copyright laws which may allow more works to be preserved. Unlike copyright law in some other countries, Canada has a "life plus 50" copyright term. This means that works by authors who died more than fifty years ago may be preserved in Canada, whereas in other parts of the world those works may not be distributed because they are still under copyright.

Notable authors whose works may be preserved in Canada but not in other parts of the world include Clark Ashton Smith, Dashiell Hammett, Ernest Hemingway, Carl Jung, A. A. Milne, Dorothy Sayers, Nevil Shute, Walter de la Mare, Sheila Kaye-Smith and Amy Carmichael.
