@DrFerrous I do find it amusing that you (and several others) read into my writing that I want to abolish paper and make everyone submit to the tyranny of ePub. I don't! You can do what you like. Fill your shelves up with paper Jeffrey Archer novels for all I care. Use the pages for bog roll if it makes you happy. I'm just happy with my choices and don't feel the need to change them just in case an EMP wipes out all computers.
