title: Is this Library Management System ER diagram correct?
body: <p>Quick question about an ER/EER Diagram.</p>
  
  <p>I have made this Entity Relationship Diagram, but I have been told, that there is something wrong with it by a friend. Is there something wrong with it? </p>
  
  <p>The ER diagram is a design of a Library Management System, where a member can borrow 5 books at a time. The rest of the functionality of the system is how a normal library functions. </p>
