The John Rylands Library looks as though it belongs in Oxford or medieval Cologne, not on a busy Manchester street beside the financial district.

When Enriqueta Rylands commissioned this neo-Gothic red sandstone building in the 1890s, she was making a statement about her late husband's legacy. John Rylands, Manchester's first multimillionaire, had built his fortune in textiles by averaging nineteen-hour workdays. His wife spent it on something rather more permanent.

The collection she assembled is extraordinary. It began with 40,000 books and grew to include a Gutenberg Bible and the oldest known fragment of the New Testament. Then there's the "Wicked Bible," a 1631 edition of the King James that accidentally instructs readers to commit adultery, courtesy of a missing "not."

VoiceMap's Manchester tours trace how industrial wealth shaped the city, using the library to show what one millionaire's conscience, and his widow's determination, built from the profits of cotton.
