Shared works - whether copyright free or made available under a free license - allow creators and users to share their knowledge and creativity with the world, in the classroom and beyond.

When a work is not protected by copyright (either by design or the expiration of a copyright term) it enters the public domain, a realm where no rights are reserved.
Open licenses, such as those provided by Creative Commons, allow copyright holders to grant permissions to users in a simple, straightforward manner, while still retaining specified rights - some rights reserved.
In copyright law, by default, all rights are reserved, or held, for the copyright holder.
