Created a UML diagram for the following scenario

The Library provides a variety of services to its students. First, the library offers a number of traditional books to be checked out by student. Each student may check out up to 5 books at one time. Although library services are offered to all students, each student must obtain a library card to check out books. The library also offers a number of computers for students use. The library tracks computer use sessions. Each student uses his/her library card number to logon and is then allowed to use the computer for up to 30 minutes per session. The library also offers movies on DVD that students may check out. The library also maintains a number of small meeting rooms that students may reserve for meetings.
