Princeton University is joining other U.S. colleges in re-examining its complicated racial legacy and will name two campus spaces for black ex-faculty members, including Nobel laureate Toni Morrison.

Morrison's name will now grace West College, one of the oldest buildings on the Ivy League campus. She was a member of the university's creative writing program until she retired in 2006. Her papers are part of the permanent library collection.

The major auditorium at the Woodrow Wilson School of Public and International Affairs will be named for Sir Arthur Lewis, another Nobel laureate who pioneered research in economic development.

The new names take effect July 1. The decision comes a year after Princeton declined to remove Wilson's name from its public policy school in response to calls that he was a segregationist.
