Creative Commons license

A Creative Commons (CC) license is one of several public copyright licenses that enable the free distribution of an otherwise copyrighted work. A CC license is used when an author wants to give people the right to share, use, and build upon a work that they have created. CC provides an author flexibility (for example, they might choose to allow only non-commercial uses of their own work) and protects the people who use or redistribute an author's work from concerns of copyright infringement as long as they abide by the conditions that are specified in the license by which the author distributes the work.

CC licensed music is available through several outlets such as SoundCloud, and is available for use in video and music remixing.

There are several types of CC licenses. The licenses differ by several combinations that condition the terms of distribution. They were initially released on December 16, 2002 by Creative Commons, a U.S. non-profit corporation founded in 2001. There have also been five versions of the suite of licenses, numbered 1.0 through 4.0. As of 2016^[update], the 4.0 license suite is the most current.

In October 2014 the Open Knowledge Foundation approved the Creative Commons CC BY, CC BY-SA, and CC0 licenses as conformant with the "Open Definition" for content and data.

Work licensed under a Creative Commons license is governed by applicable copyright law. This allows Creative Commons licenses to be applied to all work falling under copyright, including: books, plays, movies, music, articles, photographs, blogs, and websites. Creative Commons does not recommend the use of Creative Commons licenses for software.

There are over 35,000 works that are available in hardcopy and have a registered ISBN number. Creative Commons splits these works into two categories, one of which encompasses self-published books.
