Before Bill Clinton there were other presidents who at least made brief visits to Arkansas. Ongoing at the Butler Center of the Central Arkansas Library System is an exhibit on them, “Presidential Pathways in Arkansas.” Visitors to the downtown branch of the library, just off Clinton Avenue in the River Market neighborhood, will be greeted by the replica of an arch constructed when Theodore Roosevelt visited the city in 1905. The first-floor exhibit includes photos, documents and memorabilia from the 19 other presidents who have visited Arkansas (every president since Herbert Hoover). There’s also a station at which visitors can tell stories about their memories of presidential visits. They will be compiled for future readers. The second and third floors of the library have the Gallery of Presidents. Visitors can have photos taken with life-size cutouts of the former presidents. There also will be a display of political buttons and books about the Clinton presidency. Hours are 9 a.m. to 8 p.m. Monday through Thursday, 9 a.m. to 6 p.m. Friday and Saturday and 1 p.m. to 5 p.m. Sunday.
