Using new sales tax information, the Nevada County Library is projected to be $1.6 million in the hole within five years, according to a report from County Executive Officer Rick Haffey.
Projections also show the county will have a $30,000 library fund balance at the end of next fiscal year.
Haffey is expected to bring forward recommendations for alternative library models later this summer.
While the larger library system faces challenges ahead, library supporters have turned a page for the Doris Foley Library for Historical Research.
Friends of the Nevada County Libraries has donated $10,000, raised from monthly book sales, to help keep doors open at the landmark building on North Pine Street in Nevada City.
Declining sales tax revenue almost forced the closure of the Foley earlier this year, housed in a Carnegie-grant library that recently celebrated its 100th birthday.
The library will be staffed and open from 10 a.m. to 4 p.m.; the new schedule started Friday. County officials are working on an agreement with volunteers who could work additional hours.
