The Edinburgh Companion to British Colonial Periodicals is a refreshing, comprehensive, and thoroughly researched collection. Its thirty-five essays explore multiple facets of a colonial public sphere that was richly shaped by journalists, technological advancements, and political, linguistic, and imperial agendas. The editors showcase an impressive range of new research, including contributions that unearth lesser-known figures and periodicals. For researchers and scholars of the British colonial press and periodicals, this will prove to be a work with immense critical depth and potential, widening existing banks of knowledge and pointing new directions for inquiry.
