Libre/Culture

Libre works, or libre resources, are published under terms which encompass the four core freedoms first defined in the free software definition and comply with the Definition of Free Cultural Works. That is, users of the work are free to access, read, listen to, watch, or otherwise experience the resource; to learn with, copy, perform, adapt and use it for any purpose; and to contribute and share enhancements or derived works.

Some sectors of the libre culture community promote copyleft as a means of growing the commons and protecting the freedom of users and producers of derived works and mixes in future. These groups also tend to use terminology which they believe will not compromise their message.

History
The history of libre culture is linked to that of the libre software movement, Libre_knowledge and the free culture movement. These in turn have been driven by the history of copyright law which has generally become more restrictive over time.
