The table below shows an expanded subject list. These subclasses serve to further identify materials within more narrowly focused subject disciplines. When an item is cataloged it is assigned a unique callnumber based on its subject. All items in the library are assigned a unique callnumber. One especially helpful feature of the LC Class System is that items with similar subjects are located close to each other on the library shelves.
