Within each main group the principal subseries are divided by 10. For example, the history of Europe is place in the 940s. Further subdivisions eventually extend into decimal numbers. For example, the history of England is placed under 942, the history of the Stuart period at 942.06, and the history of the British Commonwealth at 942.063. The person who has borrowed the book will be asked to return it within 72 hours.
Books are subject to recall after three weeks.
Instructors sometimes put a book or an article on reserve so that all students in a class have a chance to read it. First you should check the library online catalog for the code number of the reserved item. Then go to the Circulation Desk for the reserved material. Some reserved readings may be available via electronic reserves. You can request a book or a journal article from another library.
