Where can work be registered? In Kenya, copyrighted works can be registered at the Kenya Copyrights Board for a small fee. In the United Kingdom, commercial services provide a registration facility where copies of work can be lodged to establish legal evidence of a copyright claim. In the UK, there are also requirements to file certain published works with the British Library and, on request, the five legal deposit libraries. In the United States, the United States Copyright Office accepts registrations. For works created in the US by US citizens, a registration is also required before an infringement suit may be filed in a US court. Furthermore, copyright holders cannot claim statutory damages or attorney's fees unless the work was registered prior to infringement, or within three months of publication.
