The original South Carolina State Program for Library Development 1972-1977 (ED 070 487), prepared as a means of implementing the Library Services and Construction Act--as amended by Public Law 91-600, 1970--within the state, is reviewed and revised in accordance with changing needs as demonstrated by an evaluation of current programs. Each goal of the original plan is here reviewed, with a resume of activities and accomplishments in 1973-74, and revised or extended as required by circumstances. This supplement should be used in conjunction with the original report, since background information, statistical data, standards, and criteria remain valid and have not been duplicated. (Author/SL)
