In 1922 Barton moved to the University of Pennsylvania, where he was professor of Semitic languages and the history of religion. He retired in 1931 and held the title of professor emeritus until his death. He specialized in many subjects, particularly in Semitic languages. His many publications cover a wide range of topics in areas such as biblical studies, religion, and linguistics along with translations of Sumeriancuneiform tablets.[3] He was fascinated by bible archeology and wrote a text book on the subject, published in 1916, along with other publications on similar subjects.
