Congratulations to Catharine Coleborne on the publication of Vagrant Lives in Colonial Australia: Regulating Mobility, 1840—1910 (Bloomsbury Academic). This book provides insights into the histories and identities of marginalised peoples in the British Pacific Empire. Showing how their experiences were produced, shaped and transformed through laws and institutions, it reveals how the most vulnerable people in colonial society were regulated, marginalised and criminalised in the imperial world. Defining ‘mobility’ as population movement and the occupation of new social and physical space, it offers an entry point to the related histories of penal colonies and new ‘settler’ societies. Kate Pickles has called this an ‘essential contribution to the study of mobility in precarious times’. Congratulations, Catharine!
