The Brockton Public Library will hire a consultant, through a $3,500 federal Preservation Assessment grant, to recommend ways to preserve historic library materials. It’s the first step in a long-term strategic plan for improvement of the library’s preservation environment, library director Elizabeth Marcus said. “This is a needed stepping stone that will position us for future preservation and digitization efforts,’’ she said. The project is funded through the Massachusetts Board of Library Commissioners with money from the Library Services and Technology Act, a federal source of library funding provided by the Institute of Museum and Library Services.
