In the UK, copyright expires 70 years after the death of the author. I have checked when the authors of these books died, and only republished pictures from books where the author died more than 70 years ago. I therefore believe that the original images are out of copyright.
I am not a copyright expert, and as a condition of use I will not accept liability for any breaches of copyright that result from your use of these pictures. Use and republish these pictures at your own risk. If you are to republish these images as part of a commercial project, I recommend that you consult a lawyer to ensure that you are not in breach of copyright.
If you believe I have breached your copyright, please let me know, and I will remove the pictures immediately while we investigate.
In preparing these images, I also automatically acquire copyright over these specific versions. I waive this copyright and permit my versions of these images to be used freely for any purpose whatsoever. I request, but do not demand, that you credit me or link back to the original version where possible.
