Detroit Public Library

The Detroit Public Library is the second largest library system in the U.S. state of Michigan by volumes held (after the University of Michigan Library) and the 21st-largest library system (and the fourth-largest public library system) in the United States. It is composed of the Main Library on Woodward Avenue, which houses the library's administration offices, and 23 branch locations across the city. The Main Library is part of Detroit's Cultural Center Historic District listed in the National Register of Historic Places adjacent to Wayne State University campus and across from the Detroit Institute of Arts.

Designed by Cass Gilbert, the Detroit Public Library was constructed with Vermont marble and serpentine Italian marble trim in an Italian Renaissance style. His son, Cass Gilbert Jr. was a partner with Francis Keally in the design of the library's additional wings added in 1963. Among his other buildings, Cass Gilbert designed the United States Supreme Court Building in Washington, D.C., the Minnesota State Capitol and the Woolworth Building in New York City.
