Wikibooks:How to obtain public domain books

From Wikibooks, open books for an open world
Jump to: navigation, search

There are many resources available on the net that are in the public domain, and therefore freely usable without restrictions for Wikimedia universe (this includes Wikibooks) content.

There are also many copyrighted resources whose licensing terms are liberal enough that they can generally be used as well. For these, see free or semi-free non-Public-Domain information resources and GNU Free Documentation license resources (includes images).

This page is intended as a list of only true public domain text resources. For public domain images, see public domain image resources.

CAVEAT: 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. Also, unlike the United States, most English speaking commonwealth countries exert Crown copyright. Please make certain that in any particular jurisdiction government agencies will allow you to copy materials without permission.

India government sites also seem to be copyright by default. Quoting from [1]: Unless otherwise stated, copyright and all intellectual property rights in all material presented on the site (including but not limited to text, audio, video or graphical images), trademarks and logos appearing on this site are the property of Government of Maharashtra and are protected under applicable Indian laws. Any infringement shall be vigorously defended and pursued to the fullest extent permitted by law.

Please don't data dump![edit]

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. The 1911 encyclopedia discussed below is a good example of this - it contains some useful information, but also 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 actuality 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. Wikibooks books 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 inane will eventually be tweaked and evolve into something much more sophisticated.

Encyclopedic or general resources[edit]

US Government[edit]

  • Most publications of the United States Federal Government. 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[edit]

  • 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:

Dictionaries[edit]

Other[edit]

This website contains the complete contents of the 12-volume Jewish Encyclopedia, which was originally published between 1901-1906. The Jewish Encyclopedia, which recently became part of 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 sections "Discussion Forums" and "Internet Links" which allow our visitors to converse and identify related websites.
  • ibiblio.org is a major repository of information, "the public's library and digital archive". All collections on ibiblio are assumed to be in the public domain unless otherwise noted. Check for copyright notices on any material you wish to use.

Sources for finding public domain resources[edit]

Here are some web searches which may help discover 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 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.
