Copyright notices
We respect creators’ rights. The credits page records sources and licence declarations for the materials used in this edition. If you believe material here infringes your rights, use the contact process below so we can identify and review it.
How to send a notice
Use the feedback form, select Other, and begin the message with “Copyright concern”. Identify the exact page or object and a way to reach you. Information useful for review includes:
- Your name and whether you are the rights holder or an authorized representative.
- A description of the original work and, where possible, a link to it.
- The exact URL and object name of the material on this site that you are reporting.
- A reply address where the site team can contact you.
- An explanation of the rights concern and why you believe the use is not authorized.
- Any source, licence or permission information that would help us check the report.
What happens next
Reports are saved privately for the project team. We review the identified material and may remove or disable it while resolving a concern. If you provide a reply address, we can ask for missing details or follow up. If the form’s length limit is too short, send a concise first report with a contact address.
If you believe a removal was mistaken
Send a follow-up through the same form, identify the material and the earlier report, and explain why you believe the removal was a mistake. Include any licence or permission evidence and a way to contact you. This general feedback process is not a substitute for any formal legal notice requirements.
