Linear programming Data Envelopment Analysis is used to determine the relative efficiency of 184 libraries in New York (U.S.A.). Efficiency is defined as whether or not a library could reduce the inputs it uses equiproportionately and still produce the same output. Inputs are defined programmatically: holdings, opening hours, serials and new books. Output is internal and external circulation. The subject libraries operate at just 67% efficiency, i.e., inputs could be reduced by one-third without sacrificing output if all libraries were as efficient as the benchmark 23 identified by DEA. Too many hours of opening is the main source of inefficiency.
