John Rylands Library library became one of the first to collect historical family records. Librarians at John Rylands before its merger include Edward Gordon Duff in 1899 and 1900 and Henry Guppy between 1899 and 1948 (joint Librarian with Duff until 1900). Duff was responsible for the original library catalogue, compiled between 1893 and 1899: "Catalogue of the Printed Books and Manuscripts in the John Rylands Library, Manchester"; ed. E. G. Duff. Manchester: J. E. Cornish, 1899. 3 vols. The cataloguing of the books was done by Alice Margaret Cooke, a graduate of the Victoria University. Dr Guppy began publication of the "Bulletin
Rylands v Fletcher by "Rylands". Subsequently, "Transco" disapproved of the Australian decision in "Burnie Port Authority v General Jones Pty Ltd" to absorb "Rylands" into the general law of negligence, deciding that "Rylands" should continue to exist but, as Lord Bingham said, as a "sub-species of nuisance...while insisting upon its essential nature and purpose; and...restate it so as to achieve as much certainty and clarity as is attainable". It is now a sub-tort, rather than an independent tort; they have confirmed that it will be allowed to remain. Donal Nolan has argued that to consider "Rylands" as part of private nuisance is unsound.
