{{policy|WB:MEDIA}}

This policy explains our requirements for media files used on Wikibooks, which includes images, audio and video clips. Media files which do not meet these requirements may be deleted as described in the [[WB:DP|deletion policy]].

Textbooks on Wikibooks are dual licensed under the terms of the [[WB:CC-BY-SA|Creative Commons Attribution-ShareAlike license]] and [[WB:GFDL|Wikibooks:GNU Free Documentation License]] so that anyone can freely use, modify and redistribute our books whether for free or for profit. Media files included in our books are usually licensed under similar terms, using a <span class="plainlinks">[http://freedomdefined.org/Definition free license]</span>, or they will be in the public domain. Limited use of [[#Non-free media|non-free media]] are also be allowed within the terms of this policy.

== Freely licensed or public domain media ==
{{anchor|freedoms}}

Freely licensed or public domain media must be [[c:Commons:Upload|uploaded]] to [[c:|Wikimedia Commons]], Wikimedia's shared media repository. Wikimedia Commons limits the scope of files that can be uploaded. They must comply with all the following conditions. 

Every file:

* Must be a [[C:Commons:SCOPE#Must be a media file|media file]].
* Must be of an allowable [[C:Commons:SCOPE#Must be an allowable free file format|free file format]].
* Must be [[C:Commons:SCOPE#Must be freely licensed or public domain|freely licensed or public domain]].
* Must be [[C:Commons:SCOPE#Must be realistically useful for an educational_purpose|realistically useful for an educational purpose]].

=== Freely licensed media ===
{{anchor|Free licenses}}
In countries which recognize copyright, most creative works are automatically protected by copyright. Usually the creator of the work maintains all rights to the work ("all rights reserved") unless the creator gives or transfers their copyright to someone else. This may happen through contracts or other forms of licensing. 

A '''free license''' is a license in which the copyright holders give everyone the right to use, modify, redistribute, and create derivative works of their copyrighted work for commercial or non-commercial uses. Some free licenses may have additional conditions in exchange for these rights, such as requiring all derived works to use the same license or a compatible license, including the names of all copyright holders and not using the names of copyright holders as a selling point.

Media files uploaded to Wikimedia Commons under a free license must include:

# An appropriate free [[c:Commons:Copyright tags|license template]]
# All [[commons:Commons:Licensing#License_information|information]] required by the appropriate free license, such as the name of the copyright holders and original source.

If you wish to use media or images that you created in a book on Wikibooks, you may use any free license, such as the [[WB:GFDL|GNU Free Documentation License]] or [[WB:CC BY-SA|Creative Commons Attribution-ShareAlike license]]. You may also choose to dual license your work under multiple free licenses. Dual licensing, where possible, is the preferred method because it grants maximum freedom to the users of the media. Wikimedia Commons has additional information at [[c:Commons:Licensing|Commons:Licensing]].

Unless otherwise stated by policy, free licenses must allow the four freedoms:

# The freedom to '''use''' the work and enjoy the benefits of using it
# The freedom to '''study''' the work and to apply knowledge acquired from it
# The freedom to make and redistribute '''copies''', in whole or in part, of the information or expression
# The freedom to make changes and improvements, and to distribute '''derivative''' works

These freedoms may not be restricted, and attempting to restrict these freedoms for an image or media file is grounds for immediate deletion of that file.

=== Public domain media===
{{anchor|Public domain}}
'''Public domain''' works typically have little or no protection under copyright laws, or are ineligible for copyright protection. Works may be placed in the public domain, or become public domain from the application of laws. Some countries may limit the use of public domain works or may not acknowledge public domain works at all. 

Public domain media files may be used if the media may be freely used, modified, and redistributed for commercial or non-commercial uses by anyone without restrictions or limitations.

Public domain media files uploaded to Wikimedia Commons must:

# Be in the [[c:Commons:Licensing#Material in the public domain|public domain]] in ''both'' the United States and the country of origin of the work (if they differ).
# Include an appropriate [[c:Commons:Copyright tags#Public domain|public domain template]].
# Include author [[c:Commons:Licensing#License information|information]].

If you are not the author, you must also include:

# A trusted link to where the media file can be obtained and can be easily verified as being in the public domain.
# The date the work was first created or first released.

Examples of public domain media:

* [[:File:"Baron Renfrew" 1825.jpg|Artwork]] or [[:File:(vadász) háló (heraldika).PNG|illustrations]] from the United States created by people who have been dead more than 70 years
* [[:File:0000.svg|Colors]], [[:File:25 qm Einheitskielyacht black.svg|symbols]], [[:File:Checkerboard pattern.svg|simple illustrations]], etc. ineligible for copyright

== Non-free media ==
{{shortcut|WB:FU|WB:NFCC}}{{anchor|Non-free use}}

'''Non-free media''' include all copyrighted images, audio and video clips, and other media files which lack a [[w:Free license|free license]]. Typically, they are copyrighted works used without the copyright owner's permission. For this reason, they must be uploaded locally to Wikibooks, as the uploading of non-free media to [[c:Main Page|Wikimedia Commons]] is prohibited. See [[:Category:Non-free files]] for examples of locally-uploaded non-free media. 

Local uploads of media make use of the [[Special:Upload]] page, but this is only available to [[Wikibooks:Uploaders|uploaders]] and [[Wikibooks:Administrators|administrators]]. Other users should request uploads at [[Wikibooks:Requests for import]], or else request user rights at [[Wikibooks:Requests for permissions]].

Non-free media must only be used within the strict terms of this policy. If you are unsure about non-free media use, ask about it in the [[Wikibooks:Reading room/Assistance|assistance reading room]]. This policy for non-free media is in an Exemption Doctrine Policy (EDP) in respect to the [[wmf:Resolution:Licensing policy|Wikimedia Foundation Licensing policy resolution of March 23, 2007]].<ref>This policy is largely based on English Wikipedia policy; the pages [[w:Wikipedia:Non-free content criteria|Wikipedia:Non-free content criteria]], [[w:Wikipedia:Non-free content|Wikipedia:Non-free content]], [[w:Wikipedia:Non-free use rationale guideline|Wikipedia:Non-free use rationale guideline]], and [[w:Wikipedia:Image use policy|Wikipedia:Image use policy]] may be helpful in giving it context.</ref>

=== Rationale ===
* To support Wikibooks's mission to produce perpetually [[w:free content|free content]] for unlimited distribution, modification, and application by all users in all media.
* To minimize legal exposure, by limiting the amount of non-free media, and using more narrowly defined criteria than apply under the [[w:fair use|fair use]] provisions in [[w:Copyright law of the United States|United States copyright law]].
* To facilitate the judicious use of non-free media to support the development of high-quality books.

=== Criteria ===
There is no automatic entitlement to use non-free media in a book or elsewhere in Wikibooks. They may only be used in Wikibooks when '''all 10''' of the following criteria are met.

# '''No free equivalent.''' Non-free media are only used where no freely licensed equivalent is available, that would serve the same educational purpose.
# '''Respect for commercial opportunities.''' Non-free media is not used in a manner that is likely to replace the original market role of the original copyrighted material.
# '''Minimal usage:'''
#: (a) '''Minimal number of items.''' Multiple items of non-free media should not be used, if one item can convey the equivalent significant information.
#: (b) '''Minimal extent of use'''. An entire work is not to be used if a portion will suffice. Low, rather than high, resolution—and fidelity or bit rate—should generally be used for media. The resolution of media should generally not be above 800 by 600 pixels, or 0.5 [[w:Megapixel|megapixels]].<ref>A 800 by 600 pixel image equates to 0.48 megapixels.</ref> However, this is not absolute, and higher resolution media may be uploaded with a reasonable rationale. [[w:Cropping (image)|Cropping media]] may help in achieving a lower resolution.
# '''Previous publication.''' Non-free media must be taken from a work which has been published or publicly displayed outside Wikibooks by (or with permission from) the copyright holder; or a derivative of such a work created by a Wikibooks editor.
# '''Content standards.''' Non-free media meet all general Wikibooks content standards, and are educational in nature.
# '''Media-use standards.''' Non-free media are only used in the manner described at [[Help:Files]].
# '''One-page minimum.''' Non-free media are used in at least one page.
# '''Contextual significance.''' Non-free media are used only if its presence would significantly increase readers' understanding of the topic in question, and its omission would be detrimental to that understanding.
# '''Restrictions on location.''' Non-free media are only allowed on pages in the main, Wikijunior, and Cookbook [[WB:NS|namespaces]]. To prevent an image category from displaying thumbnails, add <code><nowiki>__NOGALLERY__</nowiki></code> to it. Media should be linked, and not in-lined, from talk pages when they are a topic of discussion.
# '''Media description page.''' The media description page must contain the following:
#: (a) An appropriate [[Wikibooks:Templates/Files|non-free use template]] should be completed with the information below.
#: (b) Who the current copyright holder(s) is/are, the copyright date(s), and an identification of the source of the original copyrighted material. Where possible, any known artist(s) and publisher(s) should be listed.
#: (c) An easily identifiable [[Template:Non-free use rationale|rationale]] for why a non-free use media is required, for each instance of its use.

=== Enforcement ===
* A file with a valid non-free-use rationale for some, but not all, instances of its use will not be deleted. Instead, the file should be removed from the pages for which it lacks a non-free-use rationale, or a suitable rationale should be added.
* If a file does not otherwise comply with this policy, it can be [[WB:SPEEDY|deleted]] 48 hours after notification to the uploading editor. The uploading editor, or another editor, must provide a convincing non-free-use defense that satisfies all 10 criteria, for the file to be retained.
