4.3.2 Call Numbers

To find an item in the library you need to know the call number. The call number serves as an address. It tells you both the location and subject of the itemThe classification system is a way to shelve items on the same subject in the same area. Take a look at the Library of Congress (LC) Classification Outline. Look for the blue LC Classification Outline posters in the library to help you with browsing the collections. Hint: Think of the numbers like money... Everything behind the decimal is "change," so, in the example below, DU624.65.K495 is shelved before DU624.65.K73 because .495 "cents" is smaller than .73 "cents."
