type Book struct {
	ID    int
	Title string
	Year  int
}

func main() {
	m := map[string]Book{"foo": Book{Title: "Bar"}, "quux": Book{Title: "Baz"}}
	v := reflect.ValueOf(m)
	if v.Kind() == reflect.Map {
		for _, key := range v.MapKeys() {
			strct := v.MapIndex(key)
			fmt.Println(key.Interface(), strct.Interface())
