Consumers of content in principle have the right to use works which are in the public domain without permission and with no copyright restrictions. In practice however determining if a work has passed into the public domain can often prove difficult. This is especially true when attempting to determine the public domain status of content in multiple jurisdictions. The Public Domain Calculators available on this website answer the question of whether a certain work or other subject matter vested with copyright or neighbouring rights (related rights) has fallen into the public domain in a given European country.
