Creative Commons licenses

Creative Commons licenses are standardized public copyright licenses that let creators grant reuse permissions in advance while retaining copyright. Their conditions combine attribution with optional limits on commercial use, adaptations, and downstream licensing.

Creative Commons Attribution license: A Creative Commons license allowing copying, redistribution, and adaptation for any purpose when users give attribution. It is the least restrictive standard license in the current suite.
Copyright: A legal system granting creators exclusive rights over certain uses of original works. Creative Commons licenses grant permissions while copyright remains in force.
Creative Commons: A nonprofit organization that develops legal and technical tools for sharing creative works. It publishes and maintains the license suite.
Open access: Free online access to scholarly research, often accompanied by reuse rights. Creative Commons licenses commonly specify reuse permissions for open-access publications.
All rights reserved: A phrase indicating that a copyright holder retains all rights not explicitly granted by law or license. Creative Commons licenses replace this default posture with advance reuse permissions.
Creative Commons Attribution-ShareAlike license: A Creative Commons license permitting reuse and adaptation if attribution is given and adaptations use the same or a compatible license. Its ShareAlike condition keeps adaptations under reciprocal reuse terms.
Copyright license: A legal permission from a rights holder to perform acts that copyright would otherwise restrict. Each Creative Commons license is a standardized grant of copyright permissions.
Lawrence Lessig: An American legal scholar known for work on copyright, internet governance, and the founding of Creative Commons. He helped establish Creative Commons and articulate its approach to copyright.
Open educational resources: Teaching and learning materials that are openly licensed or in the public domain for reuse and adaptation. Their ability to be revised and redistributed often depends on license conditions.
GNU Free Documentation License: A copyleft license for documentation that permits copying and modification under specified terms. It is an alternative licensing framework historically used for collaborative reference works.
