After examining Warren County’s requirement under maintenance of effort, commissioners have left $116,000 to Magness Library in the proposed budget for fiscal year 2013-14. “The state contacted us a few years back and told us we did have a maintenance of effort that we had to meet on the library,” said Warren County Executive John Pelham. “As far as the county is concerned, we are required to do that.”Tennessee Code Annotated 10-5-101 provides the foundation for local maintenance of effort (MOE) for public libraries.
