What is the textbook fine or library fine on my statement?

Textbook fines and library fines are on student statements but they are assessed by the bookstore managers and library staff.  Bookkeepers can tell if a fine was paid, but they cannot help answer questions about why a fine was assessed.  Bookstore managers can lookup the detail on why a textbook fine was assessed.  Librarians can look up the detail on why library fines were assessed.
