The Ingalls Library is the research library of the Cleveland Museum of Art, located on floor 2R in the Marcel Breuer-designed wing on the north side of the main museum building. The library was founded in 1913 concurrent with the founding of the museum. The library is primarily used by museum employees, graduate students in Case Western Reserve University's art history program, and researchers; however, it is also open to the public. The collection of the library and archives contains "published materials covering art from all geographic areas and all periods of art history, as well as archival collections documenting the history of the Cleveland Museum of Art. Materials are collected in many languages and in all formats."
