Orphan work

Copyright-protected work for which rightsholders are positively indeterminate

An orphan work is a copyright-protected work for which rightsholders are positively indeterminate or uncontactable. Sometimes the names of the originators or rightsholders are known, yet it is impossible to contact them because additional details cannot be found. A work can become orphaned through rightsholders being unaware of their holding, or by their demise and establishing inheritance has proved impracticable. In other cases, comprehensively diligent research fails to determine any authors, creators or originators for a work. Since 1989, the amount of orphan works in the United States has increased dramatically since some works are published anonymously, assignments of rights are not required to be disclosed publicly, and registration is optional. As a result, many works' statuses with respect to who holds which rights remain unknown to the public even when those rights are being actively exploited by authors or other rightsholders.
