Opening hours at the Library of Birmingham will be slashed it has been confirmed despite an extra £200,000 being found to bolster archive services.

The city council’s cabinet member for culture confirmed that plans to axe up to 100 staff and cut opening times from 73 to 40 hours per week are still in the council’s 2015/16 budget despite widespread objections.

But an extra £200,000 has been found to support the valued archive services and will save up to ten specialist jobs. Some of the funding will also offset proposed cuts to the children’s library service.

A hoped for link up with the British Library and other potential sponsors, backers and funders are still at the negotiating stage and not likely to come through in time to make an impact on the 2015/16 budget.

Among those to lobby for protection for the archive services were a group of prominent nationally recognised photographers who have donated personal archives to Birmingham on the basis they would be looked after, regularly exhibited and made available to the public.

They said that cuts to the archives would harm Birmingham’s reputation and its status as a designated national photography collection.

Overall the Library, opened in September 2013, will still take a £1.3 million budget cut and the majority of that saving will come through reductions in staffing and opening times.

The council said last month that management were looking at the Library’s visitor statistics to select opening times which coincide with the busiest periods from Monday to Saturday.

Cabinet member for Culture Penny Holbrook (Lab, Stockland Green) speaking about the talks with outside founders, such as the British Library, said: “Talks are ongoing and three or four options are on the table.

“But they are not at the stage where we felt we could include them in the budget.”

Proposed cuts to the Birmingham Museum Trust have been postponed to future years to give the organisation time to make changes.
