Layoffs at Los Angeles' libraries will force their closure for a second day each week, beginning July 6, officials announced Thursday.

The Board of Library Commissioners reluctantly approved the new schedule, which reflects the loss of librarians under the city's $6.7 billion budget for 2010-11.

A total of 328 workers – 28 percent of the library's workforce – will be laid off this month. That leaves 828 employees to serve the Central Library, plus eight regional libraries and 64 branch libraries.

The Central Library will be closed on Sundays and Mondays; regional libraries will be closed on Sundays and have limited hours of operation through the week.

And branch libraries will be "paired," to provide the equivalent of six days of service to local patrons, officials said.

"We are still working out the details and how individual libraries will be affected," spokesman Peter Persic said.

"What we are thinking of is pairing up the libraries in an area where one would be open Monday through Friday and the second would be open Tuesday through Saturday."

Persic said patrons should check with their local libraries over the next weeks to find out the hours and days of operation.

"What we are trying to do is keep six days of service around the city," Persic said.
