With these it helps Upgrade to the latest version of AngularJS: formController.$validators is new in Angular 1.3
If you can't, refer to the documentation of yours. Here's the form guide for 1.2: https://code.angularjs.org/1.2.28/docs/guide/forms

I think the issue was by ths following , You can create a empty/dummy option above your md-option with something like
code :
<option value='null'></option>
<option ng-repeat="f in type" value="{{f}}">{{f}}</option>
<select ng-model='f.type' ng-change='toggleSelection()' ng-init='f.type = type[0]'>

this one helps. You need to play with $scope inheritance a little bit, When you use controllerAs syntax with the parent controller, If you set the name of form inside booksCtrl to vm.myForm, the form get registered to parent $scope because of prototypical inheritance of JavaScript, and you can call validation on the form in parent $scope.
code :
var app = angular.module("myApp",['listOfBooks']);
            app.controller("myCtrl", function($scope){
                $scope.authors = [];
                var vm = this;
                $scope.addAuthor = function(){
                      var author = {};
                      author.surname = "";
                      author.name = "";
                      $scope.authors.push(author);
                };
                $scope.SavelocalStorage = function(){
                    if(vm.myForm.$valid){
                        localStorage.setItem('Authors', JSON.stringify($scope.authors));
                    }
                    else{
                        alert("fill in all the gaps pls!");
                    }
                };
            });
            
            var app = angular.module("listOfBooks", []);
        app.controller("booksCtrl", function($scope) {
          $scope.showBooks = false;
        
          $scope.currentAuthor = {};
          $scope.showBookList = function(author) {
            $scope.showBooks = !$scope.showBooks;
            $scope.currentAuthor = author;
          }
        
          $scope.addBook = function() {
           
            $scope.currentAuthor.books = $scope.currentAuthor.books || [];
            var book = {};
            book.title = "";
            $scope.currentAuthor.books.push(book);
          };
        });
