This document is meant to offer guidance particularly to Wikipedians who wish to reuse ''Citizendium'' content, although our stipulations about how to attribute ''Citizendium'' articles apply to everyone.  Wikipedia will soon be able to reproduce articles, parts of articles, and other content, that originated on the ''Citizendium.''  Wikipedia may already use our versions of articles that began life on Wikipedia.

The majority of ''Citizendium'' articles, including all of its original articles, are under the [[Creative_Commons_CC-by-sa_3.0|Creative Commons Attribution-Share Alike-3.0 Unported]] license (CC-by-sa). ''[[Citizendium]]'' additionally hosts a good number of articles under the [[GNU Free Documentation License]] (GFDL) that began life at [[Wikipedia]].

The ''Citizendium'' chose the CC-by-sa for its original articles because we think it has important advantages over the GFDL, although the two provide very similar user rights.  Also, we knew that the [[Creative Commons]], [[Free Software Foundation]], and [[Wikimedia Foundation]] had expressed intent to make the CC-by-sa and GFDL compatible in the near future.  When they become so, all CC-by-sa content at ''Citizendium'' may be incorporated into Wikipedia, with proper attribution.  Currently, however, ''it is only those ''Citizendium'' articles which are explicitly licensed under the GFDL that are portable to Wikipedia'', as long as you credit ''Citizendium'' [[CZ:Sharing_Content_with_Wikipedia#How_must_I_attribute_text_I_obtain_from_Citizendium.3F|in the manner stipulated below]].

== Which articles are currently portable to Wikipedia? ==
[[Image:Wpsharescreenshot.jpg|right|thumb|400px|Image showing how to tell if a ''Citizendium'' article is GFDL.  See the red encircled text.  Unless the first phrase appears on the particular article, it is ''not'' GFDL.]]
Look at the bottom of the ''Citizendium'' article, immediately above the categories, from which you want content.  If the phrase "some content on this page may previously have appeared on Wikipedia" is present, the article is under the GFDL per the phrase that appears on all ''Citizendium'' pages, "Articles that originated in part from Wikipedia are available under GNU Free Documentation License 1.2.", e.g., see [[Cobalt]].  If ''the first phrase'' mentioned ''does not'' appear, then the article is under the CC-by-sa and ''may not'' be ported to Wikipedia, e.g., see [[Biology]].  

For a list of articles that came from outside ''Citizendium'', nearly all of which came from Wikipedia, see [[:Category:External Articles]].  Almost everything there can right now be ported back into Wikipedia.

To collaborate with other Wikipedians interested in porting ''Citizendium'' articles into Wikipedia, see [http://en.wikipedia.org/wiki/Wikipedia:WikiProject_Missing_encyclopedic_articles/Citizendium_list_of_missing_articles WikiProject Missing encyclopedic articles/Citizendium list of missing articles.]

== How must I attribute text I obtain from ''Citizendium''? ==
You must attribute ''Citizendium'' and link to http://www.citizendium.org as well as the relevant ''Citizendium'' article(s) from which you obtained text and include the date accessed.  You must display this information ''within the article'' in the same point of font as the article's main text, as well as make a note within the edit summary mentioning that you have uploaded material from ''Citizendium'' on the day you do.  Also, to avoid confusion, and until the CC-by-sa and GFDL become compatible, you must include language noting that not all text at ''Citizendium'' is under the GFDL.

:;''Example''
:{{cz
|article=Biology
|url=http://en.citizendium.org/wiki/Biology
|accessdate=30 Feb 2007
}}
In so far as it continues to meet the above requirements (it does upon [http://en.wikipedia.org/w/index.php?title=Template:Cz&diff=182282534&oldid=182282521 this edit] but may not at a later date and time), the Wikipedia template [http://en.wikipedia.org/wiki/Template:Cz <nowiki>{{Cz}}</nowiki>] is an ideal tool for giving attribution to ''Citizendium''.

We require this sort of attribution because we all contribute with our real names and have experts on board with real-life reputations to maintain.

The above also applies to derivative works of ''Citizendium'' text, such as translations.

== I'm a third party site that reuses Wikipedia and ''Citizendium'' GFDL content.  How must I attribute? ==
Third party sites that reuse ''Citizendium'' GFDL articles ''with'' Wikipedia-sourced content, and/or vice-versa, must credit ''both'' parties.  For information on attributing ''Citizendium'', see the preceding section.  For information on attributing Wikipedia, see [http://en.wikipedia.org/wiki/Wikipedia:Copyrights Wikipedia:Copyrights.]

== I can't wait until the CC-by-sa and GFDL are compatible.  What can I do?==
Until the CC-by-sa and GFDL are made explicitly compatible, ''Citizendium'' content licensed under the CC-by-sa ''may not'' be imported into Wikipedia. However, like Wikipedians, Citizens retain copyright to their work. Therefore, if the authors of a CC-by-sa article give permission for it, you can reuse their work under the GFDL (or any other terms to which they agree, for that matter).  You might also check the userpages of individual authors, since some have multi-licensed their contributions.  If you receive permission from Citizendium authors to release their work under the GFDL, you should attribute their content in the manner to which they agree, or in the absence of such, follow the selfsame guidelines as for media in the below section.

== What about media at ''Citizendium''? ==
Although ''Citizendium'' prefers media under terms compatible with Wikipedia's definition of "free", we choose  media under "less free" terms when media is otherwise unavailable or of inadequate quality.  See [[:Category:All media]] for an overview, but [[:Category:High-free media]] is where you will find media compatible with Wikimedia policies.  Everything there should be straightway importable into Wikimedia projects.

When importing articles, you will of course need to check the licensing of each instance of media therein to see if you can import it into Wikipedia along with ''Citizendium'' text that is under the GFDL.  Basically, if the licensing template of the ''Citizendium'' media instance has a <span style="color: rgb(0, 153, 0);">green background</span>, it ''should'' be good to go.  For all other media, you will need to either try to find replacements or undertake your own permissions efforts or other evaluations.

For Wikimedia-compatible media authored by ''Citizendium'' contributors, attribute it according to their stipulates and their chosen license.  If there are no specific stipulations about attribution, the default is to attribute the media to the author by name, source it to the ''Citizendium'' and link to the specific page where the media resides, and copy over its creation date and licensing data.

== What about Citizens wishing to transfer content from Wikipedia? ==
