Some colleagues were asking about Creative Commons, so I pulled together these notes. I am not a lawyer, and this post is based on a brief overview of published sources. Do not rely on this information as a substitute for legal advice
Copyrightis a broad term covering the legal protections given to the creators of written and other work, allowing them the sole right to reproduce or exploit the work for a set period, after which the work transfers to the public domain. Philosophically it is a trade-off between allowing individuals or companies to profit from their ideas, whilst ensuring that eventually ideas become part of the intellectual and cultural commons from which all humanity benefits, and thus ensuring that in the long run there is general progress in the “sciences and arts”.
The core argument of the book was that as large media corporations used their political and financial muscle to lobby for ever-longer copyright periods, and lock down media with anti-copying technology, they were increasing their profits at the expense of cultural freedom and the future creativity of the USA.
At about the same time, the Creative Commons Foundation started to create new forms of copyright licences that creators could choose to apply to their work. These new licences allow the creator of a work to choose exactly which copyright protections they wish to retain, and which they wish to set aside, in the interests of a wider usability of their work. The vision of Creative Commons is:
