Nearly seven years after Hurricane Katrina's wind and water wrecked the library at Southern University at New Orleans, restoration of the three-story structure is to begin. The library has been operating out of temporary quarters in the Multipurpose Building. A ceremony in front of the library building will launch the $4.3 million project. SUNO spokesman David Grubb said the architecture firm for the restoration is Jerry Campbell & Associates of Baton Rouge. Work is expected to be complete by next summer.
