In 1959, he wrote an article for Harper's magazine entitled, "A Machine That Does Research" which provided one of the first insights in mainstream media about how Americans' lives can change due to electronic information technology.^[4] He joined the faculty of the University of Pittsburgh in 1963, where in 1970 he began the Department of Information Science.^[5] He retired from the university in 1992.^[5] At the time of his death, he was Distinguished Service Professor in the School of Information Sciences at the University of Pittsburgh^[5] The school named a scholarship after him.^[6]
