McFarlin Library, Tulsa

At the top of Deitler Commons sits one of the campus' most notable landmarks, the McFarlin Library, which is named after Robert and Ida McFarlin, the library's primary benefactors. The McFarlins had only one stipulation with their gift, the view of Downtown Tulsa from McFarlin can never be blocked. Ground breaking ceremonies took place on May 3, 1929 and the edifice was dedicated on June 1, 1930.

The library continued to grow over the years, adding two five-story additions by 1979. Currently, the library houses over three million items and is noted for its collections of 20th-century British, Irish, and American literature, including the world's second largest collection of materials by James Joyce. It also houses the papers of Nobel Prize winner V.S. Naipaul. The library also contains a vast collection of books on Native American history. Renovations began in the spring of 2007 on a 12,000-square-foot (1,100 m2) addition that consolidated the library's computing and technology resources into one location. The library's reading rooms were restored to provide quiet areas for student and faculty study. Construction was completed in 2009.
