LSU’s Hill Memorial Library has an exhibit on two of its floors celebrating 100 years of the Cooperative Extension Service in Louisiana.

The exhibit, “Cooperative Extension at LSU: Commemorating the Centennial of the Smith-Lever Act of 1914,” features documents and photos that show the early days of a program that brought university research to small farms and families in every corner of the state. It is a presented by LSU Libraries, the LSU College of Agriculture and the LSU AgCenter, and includes photographs, oral histories, published materials, manuscript and archival records and rare books. It depicts a vastly different era, when families scratched a meager living out of the dirt, and information on improved seeds, farming methods and food safety could make a big difference in their lives.

The exhibit will be on display through Jan. 24. The library opens at 9 a.m. Mondays through Saturdays (except for days when LSU has home football games), closing at 8 p.m. Tuesdays, 1 p.m. Saturdays and 5 p.m. all other days.
