ABSTRACT This paper investigates influences upon the development of library classification systems in nineteenth-century Britain. Two case studies – Edward Edwards's ‘scheme of classification for a town library’ of 1859 and the Bibliotheca Lindesiana of the earls of Crawford who made a number of significant contributions to the development of library classification over a fifty-year period – are deployed to explore how classification schemes reflected the habituses of their creators and how they were shaped by their socio-economic, epistemological and geographical (...) contexts. The paper also investigates the discourse of classification, examining authors’ claims for the legitimacy, widespread applicability and superiority of their schemes, while revealing how these claims were compromised or modified by practical considerations. The case studies suggest that a modernizing narrative of a transition in the second half of the nineteenth century from an aristocratic, largely rural and amateur paradigm of knowledge formation to a bourgeois, urban and professional model requires significant modification: a more nuanced approach is required, which recognizes the permeability of geographic and social boundaries and the continued relevance of aristocratic libraries as key sites of knowledge formation until the end of the century.
