How to incorporate pagination feature into my repository

see the sample code

This is books model
-----------------------

publicclass Book
    {
        [Key]publicint Id { get; set; }
        [Required]
        [MaxLength(30)]publicstring Title { get; set; }publicstring Authers { get; set; }
        [Column("Year")]
        [Display(Name = "Publish Year")]publicstring publishYear { get; set; }
        [Column("Price")]
        [Display(Name = "Price")]publicdecimal BasePrice { get; set; }
    }

Repository interface
--------------------

publicinterface IBookRepository : IDisposable
        {
            IEnumerable<Book> GetBooks();
            Book GetBookByID(int bookId);void InsertBook(Book book);void DeleteBook(int bookID);void UpdateBook(Book book);void Save();
    }

Book repository
--------------------

publicclass BookRepository : IBookRepository
    {private BookContext _context;public BookRepository(BookContext bookContext)
        {this._context = bookContext;
        }public IEnumerable<book> GetBooks()
        {return _context.Books.ToList();
        }public Book GetBookByID(int id)
        {return _context.Books.Find(id);
        }publicvoid InsertBook(Book book)
        {
            _context.Books.Add(book);
        }publicvoid DeleteBook(int bookID)
        {
            Book book = _context.Books.Find(bookID);
            _context.Books.Remove(book);
        }publicvoid UpdateBook(Book book)
        {
            _context.Entry(book).State = EntityState.Modified;
        }publicvoid Save()
        {
            _context.SaveChanges();
        }privatebool disposed = false;protectedvirtualvoid Dispose(bool disposing)
        {if (!this.disposed)
            {if (disposing)
                {
                    _context.Dispose();
                }
            }this.disposed = true;
        }publicvoid Dispose()
        {
            Dispose(true);
            GC.SuppressFinalize(this);
        }
    }
