More than any other city service, libraries have extended resources through the use of volunteers. However, some believe volunteers may not be enough to keep city libraries from closing their doors for good.

San Diego City Councilman Kevin Faulconer told 10News, "I think the city has to look and be creative about how we're staffing libraries. The number of hours an employee is available, opening, closing. You want to stretch that as far as possible and be smart about it."

Michael Zucchet, general manager of the Municipal Employees Association, which represents city office workers, agreed that volunteers are valuable, but there has to be supervision.

"More volunteers may be able to put a finger in the dike here or there, but the notion that it's going to substantially change what's on the table from the mayor's office is just not going to happen," said Zucchet.

Faulconer said belts need to be tightened, but he also wants to find new sources of revenue.

"I've proposed things like revenue recovery audits, an idea of installing solar panels on city street lights that can generate millions of dollars. We have to think creatively," said Faulconer.

Zucchet said, "The issue is after six years of cutting, we are well, well, well into the bone and it's either drastic cuts or we find the money to not make these cuts. I think that's something the city council can do and the City Council will do."
