Depending upon your plan, you can return the books which are read and retain the balance books. Only in such a case while giving a request you should inform accordingly, as the exchange of books will be done only according to the books returned. (E.g. if you have a family plan and at any instance if one book and one magazine are being returned after reading, keeping back one book and one child book, in such case only one new book and one new magazine will be issued.) |
