Holding On to Reality is a brilliant history of information, from its inception in the natural world to its role in the transformation of culture to the current Internet mania and is attendant assets and liabilities. Drawing on the history of ideas, the details of information technology, and the boundaries of the human condition, Borgmann illuminates the relationship between things and signs, between reality and information.

"[Borgmann] has offered a stunningly clear definition of information in Holding On to Reality. . . . He leaves room for little argument, unless one wants to pose the now vogue objection: I guess it depends on what you mean by nothing."—Paul Bennett, Wired

"A superb anecdotal analysis of information for a hype-addled age."—New Scientist

"This insightful and poetic reflection on the changing nature of information is a wonderful antidote to much of the current hype about the 'information revolution.' Borgmann reminds us that whatever the reality of our time, we need 'a balance of signs and things' in our lives."—Margaret Wertheim, LA Weekly

While neuroscientists garner success in identifying brain regions and in analyzing individual neurons, ground is still being broken at the intermediate scale of understanding how neurons combine to encode information. This book proposes a method of representing information in a computer that would be suited for modeling the brain's methods of processing information.

Holographic Reduced Representations (HRRs) are introduced here to model how the brain distributes each piece of information among thousands of neurons. It had been previously thought that the grammatical structure of a language cannot be encoded practically in a distributed representation, but HRRs can overcome the problems of earlier proposals. Thus this work has implications for psychology, neuroscience, linguistics, and computer science, and engineering.

It is common wisdom that the U.S. economy has adapted to losses in its manufacturing base because of the booming information sector, with high-paying jobs for everything from wireless networks to video games. We are told we live in the Information Age, in which communications networks and media and information services drive the larger economy. While the Information Age may have looked sunny in the beginning, as it has developed it looks increasingly ominous: its economy and benefits grow more and more centralized--and in the United States, it has become less and less subject to democratic oversight.

Corporations around the world have identified the value of information and are now seeking to control its production, transmission, and consumption. In How to Think about Information, Dan Schiller explores the ways information has been increasingly commodified as a result and how it both resembles and differs from other commodities. Through a linked series of theoretical, historical, and contemporary studies, Schiller reveals this commodification as both dynamic and expansionary, but also deeply conflicted and uncertain. He examines the transformative political and economic changes occurring throughout the informational realm and analyzes key dimensions of the process, including the buildup of new technological platforms, the growth of a transnationalizing culture industry, and the role played by China as it reinserts itself into an informationalized capitalism.

In this age of DNA computers and artificial intelligence, information is becoming disembodied even as the "bodies" that once carried it vanish into virtuality. While some marvel at these changes, envisioning consciousness downloaded into a computer or humans "beamed" Star Trek-style, others view them with horror, seeing monsters brooding in the machines. In How We Became Posthuman, N. Katherine Hayles separates hype from fact, investigating the fate of embodiment in an information age.

Hayles relates three interwoven stories: how information lost its body, that is, how it came to be conceptualized as an entity separate from the material forms that carry it; the cultural and technological construction of the cyborg; and the dismantling of the liberal humanist "subject" in cybernetic discourse, along with the emergence of the "posthuman."

Ranging widely across the history of technology, cultural studies, and literary criticism, Hayles shows what had to be erased, forgotten, and elided to conceive of information as a disembodied entity. Thus she moves from the post-World War II Macy Conferences on cybernetics to the 1952 novel Limbo by cybernetics aficionado Bernard Wolfe; from the concept of self-making to Philip K. Dick's literary explorations of hallucination and reality; and from artificial life to postmodern novels exploring the implications of seeing humans as cybernetic systems.

Although becoming posthuman can be nightmarish, Hayles shows how it can also be liberating. From the birth of cybernetics to artificial life, How We Became Posthuman provides an indispensable account of how we arrived in our virtual age, and of where we might go from here.

In 1969, John Cage and Lejaren Hiller presented a multimedia performance that expanded the possibilities of what music and art could be. Harpsichords, computer-created tapes, films, and slides surrounded thousands of audience members while a fusion of randomness with technology gave each attendee their own unrepeatable experience.

Tiffany Funk explores how HPSCHD’s use of early computer art helped change ideas about sound, chance, and authorship. The event was less a concert than a performative system built through programming, labor, and shared decision-making. Computer art of the era required physical labor and collaboration. The impact of everything from punch cards to magnetic tape shaped the work while revealing the human effort involved. Throughout, Funk reveals that HPSCHD still offers valuable lessons about machines as collaborators rather than tools; the politics of technology; and the tension between the excitement and fears of automation.

An in-depth look at an avant-garde landmark, HPSCHD takes readers inside a legendary merger of music with computer art and its ongoing relevance in today’s digital world.

"Links" are among the most basic---and most unexamined---features of online life. Bringing together a prominent array of thinkers from industry and the academy, The Hyperlinked Society addresses a provocative series of questions about the ways in which hyperlinks organize behavior online. How do media producers' considerations of links change the way they approach their work, and how do these considerations in turn affect the ways that audiences consume news and entertainment? What role do economic and political considerations play in information producers' creation of links? How do links shape the size and scope of the public sphere in the digital age? Are hyperlinks "bridging" mechanisms that encourage people to see beyond their personal beliefs to a broader and more diverse world? Or do they simply reinforce existing bonds by encouraging people to ignore social and political perspectives that conflict with their existing interests and beliefs?

This pathbreaking collection of essays will be valuable to anyone interested in the now taken for granted connections that structure communication, commerce, and civic discourse in the world of digital media.

"This collection provides a broad and deep examination of the social, political, and economic implications of the evolving, web-based media environment. The Hyperlinked Society will be a very useful contribution to the scholarly debate about the role of the internet in modern society, and especially about the interaction between the internet and other media systems in modern society."

Cover image: This graph from Lada Adamic's chapter depicts the link structure of political blogs in the United States. The shapes reflect the blogs, and the colors of the shapes reflect political orientation---red for conservative blogs, blue for liberal ones. The size of each blog reflects the number of blogs that link to it.
