The Douglass Building was built in 1904 as the University library and the Territorial Museum. It was named after A.E. Douglass, acting president of the University in 1910 and a leader in establishing the Tree-Ring Laboratory. The building was home to the Law School from 1929-1959 followed by the Psychology Department until 1979. Currently the building houses the Dean's office for the College of Social and Behavioral Sciences, the Department of Linguistics and the Division of Late Medieval and Reformation Studies.
