What files should I upload to help prove my copyright?

We suggest that as well as the final version of your work, you include a zip file of some previous versions or a creative source file.

This helps prove the trail of creativity and originality. Please name the zip file appropriately e.g. “PreviousVersions.zip”.

This will help prove that you have exercised significant effort, skill and judgement when creating your work and demonstrates your creative choices stamping your personal touch to make the final work original.

It’s a good idea to use software source files that can visibly track and show your additions and amendments. For example, for literary work, MS word has a ‘track changes’ functionality.

For image work, an Adobe Photoshop or Illustrator can achieve the same by recording your ‘Undo’ history. It is a good to have these source files date certified by us, so please include them when uploading your work.

If some elements of your work has parts not created by you, it's important to upload copies of the licence agreement granted by them allowing you to use it.

If you have used AI (artificial intelligence) software to help create your work, we recommend you upload your AI command list which can demonstrate your human skill and judgement.

IMPORTANT NOTE for KDP, AMAZON & ACX members If any element of your book or audiobook has been purchased by you for use in your book (e.g. photo or music library material, we strongly advise you to upload a copy of the licence agreement granted to you by the copyright owner, or a signed statement from the creator that you have the legal right to use it in your work. The certificate could be rejected by these portals if you do not include this information.
