Salford Museum and Art Gallery first opened in November 1850 as "The Royal Museum & Public Library", as the first unconditionally free public library in England. The library in Campfield, Manchester was the first library to operate a "free" lending library without subscription in 1852. Norwich lays claim to being the first municipality to adopt the Public Libraries Act 1850 (which allowed any municipal borough with a population of 100,000 or more to introduce a halfpenny rate to establish public libraries—although not to buy books). Norwich was the eleventh library to open, in 1857, after Winchester, Manchester, Liverpool, Bolton, Kidderminster, Cambridge, Birkenhead and Sheffield.
