campaigners will present petitions containing more than 5,000 signatures calling for libraries in Sheffield to be kept open next month.
Sheffield City Council is considering plans to cut the number of libraries it supports which would see the Central Library and 11 others continue in their current form.
A further five would become “community libraries” where the council funds the running costs but not staff and the remaining 11 would face closure unless groups came forward to take them over.
Patrick Black, from Sheffield Communities Against Library Privatisation, said: “Once a library closes, it will be hard to re-open it. Once a library is run by volunteers, standards will decline. Once a library is transferred from council ownership, there is little control over what might be stocked, collected or provided.”
