What do materials that are not copyrighted fall under?

Materials that are not copyrighted fall under the concept of public domain. This means that these materials are no longer under the protection of copyright law and can be freely used by anyone without permission or the need to pay royalties. Works in the public domain may include those whose copyright has expired, as well as materials that were never eligible for copyright protection in the first place, such as government publications or facts and ideas.

The notion of public domain is essential for access to knowledge and culture, allowing individuals and organizations to utilize these materials for various purposes, including education, research, and creative projects. Understanding this concept is critical for individuals working in fields related to prevention and education, as it encourages the use of shared resources without legal barriers.
