Call numbers are used to organize a collection of volumes, keeping similar materials together and allowing us to find a specific item among thousands or millions of others. In general, a book's call number acts as its address on the shelf. Note: Electronic books do not have call numbers, only physical books do.

Call numbers look like this on the spine of a physical book:

PS 3511
.A86

To find a call number for a physical book through OneSearch, choose "Library Catalog" from the options to the left of the search box on the Libraries' home page.

Enter your search term in the search box and click "search" or press the "enter" key on your keyboard.

From the OneSearch results page, click on the "Material Type" limiter in the left hand column, then select "books" from the list.

Next, choose the limiter "Availability" then select "Print." 

To limit your results ONLY to physical books located in MAIN or Mullins Library, choose the limiter "Collection" then "Main Stacks."

Next, click the title of the book you want to find. This opens up a landing page for that book. Look for the call number in two places. First is at the top, where it says "Available at" then the name of a library, followed by the call number in parentheses. 

You can also find the call number listed farther down the page under "Locations:"

Lastly, if you want to see the floor location for a physical book, click the Map It! button.
