Constructed in the 1920s, the room's ceiling is sectioned in a grid-like pattern and embellished with gold, painted trim, and carvings along the top of the interior walls. Large wooden candelabra are suspended from the ceiling, and Ionic columns – echoing those on the Library's exterior – anchor three sides of the room. The main reference collection of dictionaries, encyclopedias, and bibliographies are found within Dinand as well as the on-line catalog, and a staffed reference desk.
