This document is designed to help Wisconsin libraries plan for and achieve service levels that meet the ever-changing needs of local residents. The "Wisconsin Public Library Standards" has evolved gradually over the years, and this edition addresses the changes and challenges libraries have experienced since publication of the 1994 edition. Several standards are now at higher levels to reflect the increased demands presented by new information technologies and increasing public needs and expectations for both traditional and new library services. Quantitative standards are included in this publication at four levels of effort--basic, moderate, enhanced and excellent--and are fixed for approximately 5 years. (Previous quantitative standards were published in the annual "Wisconsin Library Service Record" and updated each year, and the previous edition did not use the fourth level of effort.) Standards are outlined in the following chapters: Imperatives for Planning; How To Use these Standards; Governance and Administration; Staffing for Public Libraries; Collection and Resources; Services; and Access and Facilities. Appendices include quantitative standards by municipal population, standards by service population, and standards regardless of community size, a summary of technology-related standards, bibliography, and definitions of terms and acronyms used in the standards.
