What is stacks?
Stacks is a library term used to refer to any standard location where books and other materials are located. If an item is not in a particular location within a library (such as reference), then it is usually described as located in the stacks.
In Cook Library, the stacks includes part of the 2nd floor and all of the 3rd thru 5th floors of the building. Use the call number guide to determine which floor of the library has the item you are trying to find.
