 abstract = {Criteria for determining the efficient mix of branches, hours, stock, and new acquisitions are developed and applied to the branch operations of the New York Public Library. A method based on traveling costs is used to value library use at each branch. The relationship between library operations and library use is estimated using a two-stage technique. The costs of library operations are explored. Marginal benefit-cost ratios are presented. The study finds that the New York Public Library operates too many branches for too few hours of service.},
