Arkansas residents say the opening of the Clinton Presidential Library will help cast the state in a better light while it gives the economy a shot in the arm. Many out of state visitors to Little Rock who had invitations to yesterday`s dedication say they liked the city and wouldn`t mind returning. The library will also be an asset to state school children, who won`t have to go to Washington, DC, for a first hand look at how the federal government works. Teacher Lisa Watson says students will benefit from being able to see the exact replica of the Oval Office. Lynette Herbst of Sherwood says the historians and archivists that the library will attract will benefit the state and its young people.
