A class number, sometimes called a shelf mark number, is the number needed to help locate a book on the library shelves. At the University of Salford, we use a classification series called the Dewey Decimal System (DDC) to organise our books on the shelves. Each book is given its own class number according to this system, which you can find on the label on the spine of the book.
In order to find a book on the shelves, you will need to know its class number. You can find this information on Library Search, which shows as 'Available at'. It is normally a series of 3 numbers, followed by a number of decimal numbers and then three letters. For example, 123.123456789ABC
