A library has a collection of items (books and magazines) available to loan to its patrons. For each of the items in the collection certain information is maintained: title, author, and a unique id. In addition, a copyright year is maintained for books, and the edition number is maintained for magazines. Draw a UML class diagram representing this library information. Specify classes as appropriate, and make sure to include all required attributes. Also make sure to use inheritance if/when it is appropriate
