What license covers Wikipedia's text content as listed in its article infobox?

Wikipedia’s text content is listed in its article infobox as covered by the Creative Commons Attribution-ShareAlike 4.0 International license, commonly abbreviated CC BY-SA 4.0. The license allows people to copy, redistribute, and adapt eligible text, provided they give attribution and share adaptations under compatible terms.

The current arrangement grew out of Wikipedia’s licensing history. When the project began in 2001, its text used the GNU Free Documentation License. In 2009, after a community referendum and changes that made the licenses compatible, Wikipedia moved its main text licensing to CC BY-SA.

CC BY-SA 4.0 is not the same as CC0, which waives rights as far as legally possible, or as software licenses such as MIT and GPLv3. Wikipedia’s text licensing also has historical and dual-licensing details: much of the text is additionally available under the GFDL, while images, audio, and other media can carry separate licenses.
