ConRunner:Public domain resources

Template:Shortcut There are many resources available on the net that are in the public domain, and therefore freely usable without restrictions for Wikipedia content.

This page is intended as a list of only true public domain text resources. For other lists of resources, see below.

CAVEATS

• Because there is no concept of public domain in Japan's copyright law, even though the materials are claimed public domain, there can be some restrictions such as about commercial use, which has a conflict with GFDL.
• Unlike the United States many other countries' central-government-generated content is not in the public domain. Most English speaking commonwealth countries exert Crown copyright. Indian government sites also seem to be copyrighted by default [1]. Please make certain that in any particular jurisdiction government agencies will allow you to copy materials without permission.

Please don't data dump!

The resources below are valuable, but many are very old, context-dependent, written from biased points of view, and otherwise are not in themselves good encyclopedia articles. They contain some useful information, but also sometimes an antiquated writing style and innumerable errors of fact.

So please, if you copy material from these sources, make sure you take some time to verify the accuracy of the information: edit, update, introduce, or otherwise produce a good article out of it rather than just dumping it here verbatim. But if you can't do that, put it in anyway because somebody else will come by and tweak it. Wikipedia articles are living texts, because everybody has the power to edit them. An entry that starts out incorrect, as a stub or even as something very insane, will eventually be tweaked and evolve into something much more sophisticated.

Please include an appropriate template for the reference in article

Please use a template for the reference in an article that you create (or modify), if it exists. For example, if you include {{CIA WFB 2000}}, it expands into:

This allows us to easily locate articles that use a particular public domain source, by using the "What links here" feature on the template page: Template:CIA WFB 2000, e.g. Special:Whatlinkshere/Template:CIA WFB 2000.

A list of templates for sources (including public domain sources) can be found at: Wikipedia:Template messages/Sources of articles (note this may include templates for non-public domain sources).

Encyclopedic or general resources

US Government

• Most publications of the Federal Government of the United States. Under the Federal Copyright Act material that is originated by the Federal government is not subject to copyright. In some cases, material may originate with a private contractor which assigns the copyright to the agency. However, material that is generated by the Federal government which doesn't have a notice can be copied. Entries below marked "(US Federal Govt.)" belong to this category. Note this only applies to the Federal government. United States state governments can copyright materials.

Canadian Government

• While the Canadian government claims Crown copyright there are images archives at the National Library of Canada that are in the public domain. They include:
  • Early Images of Canada 550 images
  • Canadian Illustrated News 4000 half-tone images from 1869-1883

Dictionaries

• Hypertext Webster Gateway A searchable interface to a 1913 public-domain Webster's dictionary, downloadable here: Public Domain Dictionary
• Another searchable interface with the 1913 Webster's.

Other

• Public Domain Books: Online This website allows you to read 1,000's of Public Domain books online or download them for later reading. Also has lots of informational artcles.
• Project Gutenberg See in particular The Project Gutenberg Encyclopedia (although only Vol 1 of this seems to be available). Note that not all of the Project Gutenberg texts are fully in the public domain. Read the license of the respective texts carefully. "The Project Gutenberg Encyclopedia is a reproduction of a 1911 edition of a famous encyclopedia."
• The 1911 version of the Encyclopædia Britannica.
• The Household Cyclopedia
• The Nuttall Encyclopaedia, generally short entries, mostly about people and places; probably the only encyclopedia that does have entries about characters from Dickens' works, but not about fruit.
• The Catholic Encyclopedia (1908)
• The Jewish Encyclopedia (1901-1906)

This website contains the complete contents of the 12-volume Jewish Encyclopedia, which was originally published between 1901-1906. The Jewish Encyclopedia, which recently entered the public domain, contains over 15,000 articles and illustrations. This online version contains the unedited contents of the original encyclopedia. Since the original work was completed almost 100 years ago, it does not cover a significant portion of modern Jewish History (e.g., the creation of Israel, the Holocaust, etc.). However, it does contain an incredible amount of information that is remarkably relevant today.

We are considering inviting the Internet community to help us update the encyclopedia -- if you are interested in volunteering (as a writer, editor, etc.) please join our Mailing List. By putting this important work on the Internet, we hope to improve the quality of Jewish information available online -- and stimulate new discussion. Therefore, we have "Discussion Forums" and "Internet Links" sections which allow our visitors to converse and identify related websites.

• Web sites that contain collections that are copyright free - a lot of duplication here but some may be new.

Sources for finding public domain resources

Here are some web searches which may prove useful in the discovery of U.S. Federal Government and other public domain documents. Please note that you must still manually verify that documents are in the public domain. Please note also that not all sites in the .gov domain are U.S. federal government sites: some may be U.S. state or other local government sites.

• This Google search for '"not copyrighted" site:.gov' finds documents on websites in the .gov domain that contain the text "not copyrighted"
• This Google search for '"public domain" site:.gov' finds documents on websites in the .gov domain that contain the text "public domain"

Google searches for links or exact phrases:

• "this document is in the public domain" (estimated 2500+ hits)
• "this page is in the public domain" (estimated 1000+ hits)
• "this information is in the public domain" (estimated 1000+ hits)
• "this text is in the public domain" (estimated 2000+ hits)
• "placed in the public domain" (estimated 24000+ hits, but many instances refer to other things)
• "www.ethicalpublicdomain.org" (find links confirming that a site is Public Domain)
• Creative Commons Public Domain Dedication

The Creative Commons initiative may become a valuable new resource for Wikipedia authors. The project provides a "wizard" for licensing information under various open content licenses (including the public domain, which is not a license), and also features a directory of these works.
