48 What is the public domain?
The public domain refers to material for which no copyright exists. In most instances, copyright for these items has expired. However, there are several cases where the author or creator has decided to release their work into the public domain by waiving all copy and related rights. For this, a CC0, "no rights reserved", logo is often used.
