Morris worked at: Librarian, Univ. SD 1941-43; Patent chemist, Hercules Powder Co. 1943-1946; Chief librarian, Oak Ridge National Laboratory (ORNL) 1947-54. He wrote Corporate Entry Guide for Report Literature at ORNL as well as two important articles on subject analysis. Under his leadership the ORNL library became a model special library. He developed an “outstanding technical reports control system.” Morris was responsible for the basic ideas/systems used to catalog the series reports issued by the AEC. He challenged Taube’s Uniterm information retrieval system. He believed subject headings used in a unit card system of application were superior to the Uniterm system. He advocated the development of a system combining the best features of unit and marginal punched cards.
