The John Rylands Research Institute and Library is a late-Victorian neo-Gothic building on Deansgate in Manchester, England. It is part of the University of Manchester. The library, which opened to the public in 1900, was founded by Enriqueta Augustina Rylands in memory of her husband, John Rylands. It became part of the university in 1972, and now houses the majority of the Special Collections of The University of Manchester Library, the third largest academic library in the United Kingdom .
Special collections built up by both libraries were progressively concentrated in the Deansgate building. The special collections, believed to be among the largest in the United Kingdom, include medieval illuminated manuscripts and examples of early European printing, including a Gutenberg Bible and a Mainz Psalter, the second largest collection of printing by William Caxton, and the most extensive collection of the editions of the Aldine Press of Venice. The Rylands Library Papyrus P52 has a claim to be the earliest extant New Testament text. The library holds personal papers and letters of notable figures, among them the novelist Elizabeth Gaskell and the scientist John Dalton.
