1. Are books and DVDs the only two types of items that are and will be available in the library or should be act as there could be different types in the future?
2. Is there a minimal year of the publishing of the book (e.g. year 1000, or 500, or 0, or even BC)?
3. Does the library have any  limit on the number of readers?
4. Would the library want to store information on every reader forever or should the option of deleting a reader be enabled? 
5. If an item was borrowed at a certain time, e.g. 10:50, should it be returned until 10:50, 3 (or 7) days later or until midnight (as in a real-life library)?

It is not always necessary to specify time in real life (e.g. for the publication date). Would it be acceptable to create two constructors for this class, one with hours and minutes and the other one without or should the time be always specified? If it doesn't have to be, is there any default time (e.g. 00:00 or 12:00) that would be set if the time was not specified? It is relevant taking into account the fee. If the manager does not input time, just a date, from which hour will the fee be calculated? Or, if every DateTime needs to have time, even for a publishing, with only one constructor, should there be any default time for that?]]> 2018-11-04 14:04:50 UTC https://padlet.com/b_villarini/wz7ga6pop9n1/wish/300180504 https://padlet.com/b_villarini/wz7ga6pop9n1/wish/300192747 When calculating the fee, should we take into account different number of days of certain months and leap years or is it expected to be simplified?]]> 2018-11-04 15:27:35 UTC https://padlet.com/b_villarini/wz7ga6pop9n1/wish/300192747 https://padlet.com/b_villarini/wz7ga6pop9n1/wish/300204030 Is the reader class, a subclass of LibraryItem?
