Call numbers are a combination of letters and numbers. A call number is like a street address and the collection designation is like a city. These two pieces of information tells us where the item is located in the library.

All the library's books and media are arranged by the Library of Congress classification system.

Our board games do not have call numbers. They are displayed for browsing.

The magazines, journals and microfilm are arranged alphabetically.

The government documents collection is arranged by the Superintendent of Documents classification system.

When searching the library catalog the collection information and call number are both visible on the results screen.

In this example from the library catalog

the collection is Ole's Oasis

the call number is PS3616.A86673 K35 2022

The call number label is most often located on the bottom of the spine or side of the item.
