Q. Where is my book located in the library?
When you find a book in IUCAT, it will have a “Call Number,” which is like a book’s address (for example: F526.5 .I53, Stacks). The library’s collection is divided into 21 categories indicated by single letters of the Roman alphabet, with major subdivisions indicated by a second letter, and narrower subdivisions by decimal numbers, and further alphabetic notation. Floor maps are located throughout the library, at the Service & Information desk and show where the major categories are located in the “stacks,” or shelving.
