Drive the streets of Nairobi and you are sure to see many matatus colorful minibuses that transport huge numbers of people around the city. Once ramshackle affairs held together with duct tape and wire, matatus today are name-brand vehicles maxed out with aftermarket detailing. They can be stately black or come in extravagant colors, sporting names, slogans, or entire tableaus, with airbrushed portraits of everyone from Kanye West to Barack Obama, of athletes, movie stars, or the most famous face of all: Jesus Christ. In this richly interdisciplinary book, Kenda Mutongi explores the history of the matatu from the 1960s to the present. As Mutongi shows, matatus offer a window onto many socioeconomic and political facets of late-twentieth-century Africa. In their diversity of idiosyncratic designs they express multiple and divergent aspects of Kenyan life including rapid urbanization, organized crime, entrepreneurship, social insecurity, the transition to democracy, chaos and congestion, popular culture, and many others at once embodying both Kenya's staggering social problems and the bright promises of its future. Offering a shining model of interdisciplinary analysis, Mutongi mixes historical, ethnographic, literary, linguistic, and economic approaches to tell the story of the matatu as a powerful expression of the entrepreneurial aesthetics of the postcolonial world.

There are few places where mobility has shaped identity as widely as the American West, but some locations and populations sit at its major crossroads, maintaining control over place and mobility, labor and race. In Collisions at the Crossroads, Genevieve Carpio argues that mobility, both permission to move freely and prohibitions on movement, helped shape racial formation in the eastern suburbs of Los Angeles and the Inland Empire throughout the nineteenth and twentieth centuries. By examining policies and forces as different as historical societies, Indian boarding schools, bicycle ordinances, immigration policy, incarceration, traffic checkpoints, and Route 66 heritage, she shows how local authorities constructed a racial hierarchy by allowing some people to move freely while placing limits on the mobility of others. Highlighting the ways people of color have negotiated their place within these systems, Carpio reveals a compelling and perceptive analysis of spatial mobility through physical movement and residence.

Containing contributions exploring transport and mobility history after 1800, this volume of eclectic chapters shows how new subjects are explored, new sources are being encountered, considered and used, and how increasingly diverse and innovative methodological lenses are applied to both new and well-travelled subjects.
