1. copy list of object

You need to create new Book objects then put those in a new List:

List<Book> books_2 = books_1.Select(book => new Book(book.title)).ToList();

Update: Slightly simpler... List<T> has a method called ConvertAll that returns a new list:

List<Book> books_2 = books_1.ConvertAll(book => new Book(book.title));

2. copy list of primitive types (string)

List<string> a = new List<string>{"C","P"};

var b = new List<string>(a);
