The kaleidoscope, the stereoscope, and other nineteenth-century optical toys analyzed as "new media" of their era, provoking anxieties similar to our own about children and screens. In the nineteenth century, the kaleidoscope, the thaumatrope, the zoetrope, the stereoscope, and other optical toys were standard accessories of a middle-class childhood, used both at home and at school. In Playful Visions, Meredith Bak argues that the optical toys of the nineteenth century were the "new media" of their era, teaching children to be discerning consumers of media-and also provoking anxieties similar to contemporary worries about children's screen time. Bak shows that optical toys-which produced visual effects ranging from a moving image to the illusion of depth-established and reinforced a new understanding of vision as an interpretive process. At the same time, the expansion of the middle class as well as education and labor reforms contributed to a new notion of childhood as a time of innocence and play. Modern media culture and the emergence of modern Western childhood are thus deeply interconnected. Drawing on extensive archival research, Bak discusses, among other things, the circulation of optical toys, and the wide visibility gained by their appearance as printed templates and textual descriptions in periodicals; expanding conceptions of literacy, which came to include visual acuity; and how optical play allowed children to exercise a sense of visual mastery. She examines optical toys alongside related visual technologies including chromolithography-which inspired both chromatic delight and chromophobia. Finally, considering the contemporary use of optical toys in advertising, education, and art, Bak analyzes the endurance of nineteenth-century visual paradigms.

How Silicon Valley, the dark net, and digital culture have affected our relationship to knowledge, history, language, aesthetics, reading, and truth. In October 2013, twenty-nine-year-old Ross William Ulbricht was arrested at the Glen Park Public Branch Library in San Francisco, accused of being the "Dread Pirate Roberts" and mastermind of a dark net drug marketplace known as Silk Road. Ulbricht was an ardent libertarian who believed Silk Road-described by the New York Times as "the largest, most sophisticated criminal enterprise the internet has ever seen"-was battling the forces of big government. He was convicted two years later of money laundering, computer hacking, and conspiracy to traffic narcotics and sentenced to life in prison. Art historian Pamela Lee reads this event as a fairy tale of disruption rather than an isolated episode in the history of the dark net, Silicon Valley, and the relationship between public libraries and digital culture. Lee argues that the notion of "disruptive" technology in contemporary culture has radically affected our relationship to knowledge, history, language, aesthetics, reading, and truth. Against the backdrop of her account of Ulbricht and his exploits, Lee provides original readings of five women artists-Gretchen Bender, Cecile B. Evans, Josephine Pryde, Carissa Rodriguez, and Martine Syms-who weigh in, either explicitly or inadvertently, on the nature of contemporary media and technology. Written as a work of experimental art criticism, The Glen Park Library is both a homage to the Bay Area and an excoriation of the ethos of Silicon Valley. As with all fairy tales, the book's ultimate subjects are much greater, however, and Lee casts a critical eye on collisions between privacy and publicity, knowledge and information, and the past and future that are enabled by the technocratic worldview.

In this provocative book, C. Edwin Baker argues that print advertising seriously distorts the flow of news by creating a powerfully corrupting incentive: the more newspapers depend financially on advertising, the more they favor the interests of advertisers over those of readers. Advertising induces newspapers to compete for a maximum audience with blandly "objective" information, resulting in reduced differentiation among papers and the eventual collapse of competition among dailies.
