Ruskington library, which falls into to the lowest category of community libraries, could see its hours cut from 22 hour a week to just 12, which is one of the severest proposed cuts.

It could be good news for Sleaford library, however, which is classed in the top category of district libraries and could have its hours increased from 48 to 54.

John Pateman, head of Libraries, Learning and Inclusion, said: "Lincolnshire County Council has undertaken a major review of the library service over the past year, including multiple consultations with the public, staff and stakeholders. The library network is not sustainable in its current form.

"The proposals that came out of this review involved the short-term stabilisation of the library budget by enhancing opening hours in groups of libraries. Libraries within a reasonable travelling distance will have opening hours that provide a service in the mornings, afternoons, evenings and on Saturdays.

"We are currently in the process of developing those hours, based on when each library is most-used. This exercise hasn't been completed yet and changes are subject to consultation with councillors and staff."

He added: "From 2009 there are longer-term plans to develop the library service and work in partnership with other groups and service providers to improve access to public services through libraries, to meet the needs of local communities.

"It is planned that the new opening hours will come into effect from April."

The staff consultation process will end on February 29 and new library opening hours will be confirmed on March 1.
