• In 1860, the newly-appointed librarian of the Royal Library at Windsor Castle, Bernard Bolingbroke Woodward, drew up a series of ambitious plans aimed at reforming the organisation and administration of the collection. The work carried out on the library during this period included the introduction of a subject-based classification system and the first concerted attempts made to produce a library catalogue. Woodward’s re-development of the library was undertaken at the express behest of Prince Albert, the Prince Consort, and, in several aspects, under his direct influence. This study examines the historical contexts and influences that went into shaping the redevelopment of the library in the 1860s, with a view towards gaining a more detailed understanding of rationale behind the plans for the reorganisation of this collection. The research is carried out through an historical study by means of extended review of the secondary literature, together with a close analysis of the major primary sources in the form of reports produced by Woodward in which he details his vision and his recommendations for the library. The historical connections to other contemporary libraries are mapped, and the context also sought for the classification scheme introduced by the Prince Consort.
