A program that allows Southern Oregon University students short-term access to expensive textbooks at the Hannon Library is scheduled to end June 11 because of budget constraints, university officials said. Since 2002, a copy of every textbook that costs $100 or more has been given to the library by the SOU Bookstore and placed on reserve for students to check out for library use only for a maximum of four hours. Neither students nor faculty were notified of the decision to end the textbook program.
