In 1893, a Psychology Laboratory was established in Nassau Hall. One of the four rooms of this laboratory served as a library. In 1920, the Department of Psychology was founded by a separation from the Department of Philosophy. In 1924, Eno Hall was built for the Psychology Department and one room was set aside as the library. Eno Hall was the very first building of any university in the United States, built for the exclusive study of Psychology. In 1963, when the Psychology Department moved to Green Hall (the former engineering building) on the corner of Washington and William Streets, one room next to the lobby served as the library. By 1968, a second and third room had been added for monograph and journal stacks. In 1990, the third room was moved into the basement to accommodate compact shelving for the bound journal collection.

During the summer of 2002, the Psychology Library underwent major renovations. The library was temporarily moved out of its space for the major overhaul. When the work was completed in September of 2002, it no longer had the basement room but it gained the stunning “Langfeld Reading Room” which has seating for 24 people, with 18 electric hook-ups for laptops as well as wireless internet. A customized Circulation Desk was added. The staff moved into the office previously occupied by the librarian and a new librarian’s office was built next to one of the computer clusters. A new glass display case at the front of the library houses the books by the department’s faculty.

In 2013, the Psychology Department and Neuroscience Institute will be moved to a stunning new building in the Science neighborhood ( To prepare for the move, the Psychology library was moved out of Green Hall in June of 2011 and into the Lewis Library.
