Manning's Post Office was established in 1856, and Thomas S. Coogler was appointed as the first Postmaster. Manning's first library, the Hannah Levi Memorial Library, was completed in 1910. It was funded by the children of Moses and Hannah Levi, and by the sale of the Moses Levi Institute. They named it in honor of their mother. It eventually became known as the Manning Library and was the only public library in the county. It became a county library in 1976 and continued to operate until the opening of the Harvin Clarendon County Library in 1984. The building now houses the Clarendon County Archives and History Center.
