This book is a hardcover, not "unknown". It is a Barnes & Noble Book and is part of their series of books for kids, all entitled "1000 Facts On..."
A really cool book with color pictures on every page. This one is about the physical world: volcanoes, earthquakes, weather, continents, oceans, formation of the earth, etc.
