Since their origins in eighteenth-century England, railroads have spread across the globe, changing everything in their path, from where and how people grew and made things to where and how they lived and moved. Railroads rewrote not only world geography but also the history of maps and mapping. Today, the needs of train companies and their users continue to shape the maps we consume and consult.

Featuring full-color maps primarily from the British Library's distinguished collection--many of them never before published--A History of the Railroad in 100 Maps is the first international history of railroads and railroad infrastructure told through maps. Jeremy Black includes examples from six continents, spanning a variety of uses from railroad planning and operations to guides for passengers, shippers, and tourists.

Arranged chronologically, the maps are accompanied by explanatory text that sheds light on the political, military, and urban development histories associated with the spread of railroads. A final chapter considers railroad maps from games, books, and other cultural artifacts. For anyone interested in the history of railroads or maps, A History of the Railroad in 100 Maps (U Chicago Press, 2024) will offer new and unexpected insights into their intertwined global history.

Digital technologies have changed how we shop, work, play, and communicate, reshaping our societies and economies. To understand digital capitalism, we need to grasp how advances in geospatial technologies underpin the construction, operation, and refinement of markets for digital goods and services. 

In The Map in the Machine: Charting the Spatial Architecture of Digital Capitalism (U California Press, 2024), Luis F. Alvarez Leon examines these advances, from MapQuest and Google Maps to the rise of IP geolocation, ridesharing, and a new Earth Observation satellite ecosystem. He develops a geographical theory of digital capitalism centered on the processes of location, valuation, and marketization to provide a new vantage point from which to better understand, and intervene in, the dominant techno-economic paradigm of our time. By centering the spatiality of digital capitalism, Alvarez Leon shows how this system is the product not of seemingly intangible information clouds but rather of a vast array of technologies, practices, and infrastructures deeply rooted in place, mediated by geography, and open to contestation and change.

Surround sound is often mistaken as a relatively new phenomenon in cinemas, one that emerged in the 1970s with the arrival of Dolby. Making Stereo Fit: The History of a Disquieting Film Technology (University of California Press, 2024) reveals that, in fact, filmmakers have been creating stereo and surround-sound effects for nearly a century, since the advent of talking pictures, and argues that their endurance owes primarily to the longstanding battles between stereo and mono technologies. 

Throughout the book, Eric Dienstfrey analyzes newly discovered archival materials and myriad stereo releases, from Hell’s Angels (1930) to Get Out (2017), to show how Hollywood’s financial dependence on mono prevented filmmakers from seeing surround sound’s full aesthetic potential. Though studios initially explored stereo’s unique capabilities, Dienstfrey details how filmmakers eventually codified a conservative set of surround-sound techniques that prevail today, despite the arrival of more immersive formats.

Revolutions in technology are fundamentally transforming what it means to be human. Or are they? As Webb Keane points out, before humans consulted ChatGPT, they propitiated oracles. Before they fell in love with robot boyfriends, they ventured into the forest to marry nature spirits. 

In his new book Animals, Robots, Gods: Adventures in the Moral Imagination (Princeton UP, 2025) Keane combines anthropology and philosophy to show us what is new and what is not in our current technological moment. Using a broad comparative perspective he shows us how shamans, hunters, priests, and doctors have long responded to the existential questions which drive our current technological obsessions: Where is the line between human and non-human? How do humans find meaning in our interactions with non-humans? By widening our intellectual imagination, Keane shows us how many of our current intellectual dilemmas about technology are not new -- and are far more deep than enduring than we might have previously suspected.

Webb Keane is the George Herbert Mead Distinguished University Professor in the Department of Anthropology at the University of Michigan.

Alex Golub is an associate professor of anthropology at the University of Hawai‘i at Mānoa

How epidemic photography during a global pandemic of bubonic plague contributed to the development of modern epidemiology and our concept of the “pandemic.”

In Visual Plague: The Emergence of Epidemic Photography (MIT Press, 2022), Christos Lynteris examines the emergence of epidemic photography during the third plague pandemic (1894–1959), a global pandemic of bubonic plague that led to over twelve million deaths. Unlike medical photography, epidemic photography was not exclusively, or even primarily, concerned with exposing the patient's body or medical examinations and operations. Instead, it played a key role in reconceptualizing infectious diseases by visualizing the “pandemic” as a new concept and structure of experience—one that frames and responds to the smallest local outbreak of an infectious disease as an event of global importance and consequence.

As the third plague pandemic struck more and more countries, the international circulation of plague photographs in the press generated an unprecedented spectacle of imminent global threat. Nothing contributed to this sense of global interconnectedness, anticipation, and fear more than photography. Exploring the impact of epidemic photography at the time of its emergence, Lynteris highlights its entanglement with colonial politics, epistemologies, and aesthetics, as well as with major shifts in epidemiological thinking and public health practice. He explores the characteristics, uses, and impact of epidemic photography and how it differs from the general corpus of medical photography. The new photography was used not simply to visualize or illustrate a pandemic, but to articulate, respond to, and unsettle key questions of epidemiology and epidemic control, as well as to foster the notion of the “pandemic,” which continues to affect our lives today.

Christos Lynteris is Professor of Medical Anthropology at the University of St Andrews. His research focuses on the anthropological and historical examination of epidemics with a particular focus on zoonotic diseases, epidemiological epistemology, visual medical culture, and colonial medicine. His regional expertise includes China and Inner Asia.

Professor Lynteris holds the first chair in medical anthropology at the University of St Andrews. Focusing on diseases that spread between animals and humans, his research has been foundational in the establishment of the anthropological study of zoonosis. Combining archival and ethnographic research together with visual methods and critical approaches to medical and epidemiological epistemologies, Professor Lynteris's research seeks to understand how specific zoonotic diseases (SARS, COVID-19, plague) and the broader question of zoonosis shape social and multispecies worlds and are in turn shaped by them.

My guest today Sam Srauy is an Associate Professor in the Department of Communication, Journalism, and Public Relations at Oakland University, Her research examines race, video games, and the political economy of the video game industry. Srauy’s work appears in various academic journals including Social Media + Society, First Mondays, Games and Culture, and Television and New Media. She teaches courses on identity, race/racism, digital media production, and video game studies/production. Prior to academia, Srauy worked for over a decade in the high-tech industry. Her experience in that field includes municipal wireless networks, open-source technology, and streaming media systems. About the book: 

Race, Culture and the Video Game Industry: A Vicious Circuit (Routledge, 2024) offers a detailed and much needed examination of how systemic racism in the US shaped the culture, market logic, and production practices of video game developers from the 1970s until the 2010s.

Offering historical analysis of the video game industries (console, PC, and indie) from a critical, political economic lens, this book specifically examines the history of how such practices created, enabled, and maintained racism through the imagined 'gamer.' The book explores how the cultural and economic landscape of the United States developed from the 1970s through the 2000s and explains how racist attitudes are reflected and maintained in the practices of video games production. These practices constitute a 'Vicious Circuit' that normalizes racism and the centrality of an imagined gamer identity. It also explores how the industry, from indie game developers to larger profit-driven companies, responded to changing attitudes in the 2010s, where racism and lack of diversity in games was frequently being noted. The book concludes by offering potential solutions to combat this 'Vicious Circuit'.

A vital contribution to the study of video games that will be welcomed by students and scholars in the fields of media studies, cultural studies, game studies, critical race studies, and beyond.

Peoples & Things host, Lee Vinsel, talks with Aure Schrock, an interdisciplinary technology scholar and writing coach and editor at Indelible Voice, about their book, Politics Recoded: The Infrastructural Organizing of Code for America (MIT Press, 2024)

Politics Recoded examines the history and culture of Code for America, an organization that, as one of its leaders put it, aimed “to promote ‘civic hacking,’ and to bring 21st century technology to government.” The book describes how the organization has changed over time from a “tech-forward” vision rooted in techno-libertarianism to an organization that provides something like digital consulting services to governments. The pair also talk about Aure’s writing and editing company, the Indelible Voice, and what it’s like helping scholars refine their vision and voice in academic writing.
