In October 2010, Library Journal announced its latest Index of Public Library Service, and Worthington Libraries once again received a five-star rating the best possible in its category of libraries with total annual operating expenditures of over $5 million but less than $10 million.
To be included, a library must achieve four criteria:
- meeting the Institute of Museum & Library Services definition of a public library,
- having $10,000 or more in total operating expenditures annually,
- serving a legal service area population of 1,000 or more residents, and
- reporting all of the four service indicators used in the index: library visits, circulation, program attendance and public Internet computer uses.
Libraries were evaluated on each service indicator relative to the performance of other libraries in their peer group.
Over 7,000 libraries across the country were evaluated, but only 258 received a starred rating. Only 85 libraries received a five-star rating.
Worthington Libraries was ranked fourth in its peer group, behind only the Upper Arlington Public Library in Upper Arlington, Ohio, the Westerville Public Library in Westerville, Ohio and the Shaker Heights Public Library in Shaker Heights, Ohio.
