The CUI Library has two levels, the main floor and the lower floor. Any location listed in italics can be found on the floorplan.

The main floor is home to the Circulation Desk, the Reference Desk, the Reserve Collection, the Reference Collection, the Copier Room, six research stations, two lounges, the Periodical Collection, the Robert C. Baden Memorial Children's Collection, the Dale Hartmann Curriculum Room, and five conference rooms.

The long desk to the left of the entrance combines the Circulation Desk, the Reference Desk, and the Reserve Collection. A CUI ID card is required to check out any material from the Library. This includes books, video tapes, audio tapes, CDs, and equipment. The Reserve Collection contains items the faculty deem particularly important for students in their particular classes to examine. Because so many students will need to access them, they have special loan periods: library use only, 3 hour, overnight, and seven days. No item can be given a longer loan period without written permission from the professor.

The Reference Collection is located just past the Circulation Desk. Books in this collection can NOT be checked out. Adjacent to the Reference Collection is the Copier Room. A photocopier/printer, photocopier, and laminating machine are all located in this room. Copies or prints cost 10 cents a piece. Each machine takes nickels, dimes, quarters, dollars, fives, tens, and twenties. They also have the ability to take money from the CUI ID card. An add value station is available at the end of the Circulation Desk.

Six Research Stations are located at the top of the stairs. These machines give access to the library's catalog, subscription databases, as well as the Internet. They do not have word processing programs or email clients. The campus computer labs (currently located in the Student Success Center, Chi Rho, and Chi Sigma) provide access to email and the Microsoft Office programs.

The library's Periodical Collection, including current periodicals, bound periodicals, and periodicals on microfiche, are all located on this level. The current periodicals are located on the shelves closest to the Research Stations. The bound, or older periodicals, are located on the shelves in the middle of the main floor. The Periodical Collection is cataloged alphabetically by title. Periodicals in the microfiche collection can be accessed by asking at the Circulation Desk.

The Robert C. Baden Memorial Children's Collection is located in the middle of the Bound Periodicals. This collection is the only Dewey Decimal Collection at CUI. The collection of over 3,500 items includes all Caldecott and Newbery award winning titles.

The CUI Library has two Lounge areas with couches and armchairs located on the west end of the building. The north side of the building contains five Conference Rooms for group study. Conference Rooms are only available to patrons with a CUI ID card. Reservations and access are available at the Circulation Desk.

The Dale Hartmann Curriculum Room (LA 101) is home to the library's collection of elementary and secondary school curriculum sets. This collection covers most subject areas and grade levels.
