Historic New Orleans Library

The Historic New Orleans Collection is a museum, research center, and publisher dedicated to the study and preservation of the history and culture of New Orleans and the Gulf South region of the United States. It is located in New Orleans' French Quarter. The institution was established in 1966 by General and Mrs. L. Kemper Williams to keep their collection of Louisiana materials intact and available for research and exhibition to the public.

The Collection operates a museum, which includes the Williams Gallery, Louisiana History Galleries, the Williams Residence, a house museum, and a museum shop. The Williams Research Center, which opened in 1996, makes The Collection's holdings available to researchers.
