I would recommend this book to anyone who had an interest in super-conducting materials, or material science in general. It could be understood by anyone that had a secondary school level of science education, but I still found it interesting and informative as someone with a doctorate in materials science. I will be recommending this book to my colleagues in material science as well as my friends working in admin.
