Shaun at the Book Inscriptions Project wrote to us:
We are trying to collect as many book inscriptions as we can from all around the world so we can put up a new one every day.
Some of them are funny, some are sad, some are just unbelievably personal. We would love to see the ones you've found over the years.
This one above is a 1935 copy of Victoria Regina: A Dramatic Biography by Laurence Housman, with the inscription:
"Miss E Frances. With my dear love. It is forbidden to laugh at Royalty."
