If a book is not available for borrowing, a reservation can be made and added to the reservation queue of the book. The library will send a note to the one whose reservation is on the top of the queue when the book is available. When a book is overdue, a fine will be started which will build up each day.

Journals and magazines can be recommended only by researcher. These recommendations will be reviewed and approved by a Librarian.
