While the legal ownership of the Company’s knowledge resources could be transferred to the Crown with the passage of a new charter, just what it meant to be a “public” knowledge resource was up for debate. In this period, just as natural philosophy was resolving into separate disciplines with separate institutional structures, the cultural space of knowledge production was separating into new and separate spheres: public versus private, national versus imperial, professional versus amateur. The Company’s piecemeal absorption into the British state was not so much the erasure of a historical anomaly but part of the very process by which “states” and “publics” came to be more clearly defined against corporations and “private” interests. This chapter considers how the public–private status of the Company was also debated and constructed in relation to science, education and access to knowledge resources. At a time when a coherent British imperial identity was only just beginning to crystallize, the extremely convoluted property relations for the library-museum (held in trust by the Company for the Crown, which in turn held it in trust for the people of British India) raised awkward questions about the very coherence of the idea of an imperial public.
