What are the future prospects for literary knowledge now that literary texts—and the material remains of authorship, publishing, and reading—are reduced to bitstreams, strings of digital ones and zeros? What are the opportunities and obligations for book history, textual criticism, and bibliography when literary texts are distributed across digital platforms, devices, formats, and networks? Indeed, what is textual scholarship when the "text" of our everyday speech is a verb as often as it is a noun? These are the questions that motivate Matthew G. Kirschenbaum in Bitstreams, a distillation of twenty years of thinking about the intersection of digital media, textual studies, and literary archives. With an intimate narrative style that belies the cold technics of computing, Kirschenbaum takes the reader into the library where all access to Toni Morrison's "papers" is mediated by digital technology; to the bitmapped fonts of Kamau Brathwaite's Macintosh; to the process of recovering and restoring fourteen lost "HyperPoems" by the noted poet William Dickey; and finally, into the offices of Melcher Media, a small boutique design studio reimagining the future of the codex. A persistent theme is that bits—the ubiquitous ones and zeros of computing—are never self-identical, but always inflected by the material realities of particular systems, platforms, and protocols. These materialities are not liabilities: they are the very bulwark on which we stake the enterprise for preserving the future of literary heritage.

A leading voice in technology studies shares a collection of essential essays on the preservation of software and history of games. Since the early 2000s, Henry Lowood has led or had a key role in numerous initiatives devoted to the preservation and documentation of virtual worlds, digital games, and interactive simulations, establishing himself as a major scholar in the field of game studies. His voluminous writings have tackled subject matter spanning the history of game design and development, military simulation, table-top games, machinima, e-sports, wargaming, and historical software archives and collection development. Replayed consolidates Lowood's far-flung and significant publications on these subjects into a single volume.

The story of writing in the digital age is every bit as messy as the ink-stained rags that littered the floor of Gutenberg's print shop or the hot molten lead of the Linotype machine. During the period of the pivotal growth and widespread adoption of word processing as a writing technology, some authors embraced it as a marvel while others decried it as the death of literature. The product of years of archival research and numerous interviews conducted by the author, Track Changes is the first literary history of word processing. Matthew Kirschenbaum examines how the interests and ideals of creative authorship came to coexist with the computer revolution. Who were the first adopters? What kind of anxieties did they share? Was word processing perceived as just a better typewriter or something more? How did it change our understanding of writing? Track Changes balances the stories of individual writers with a consideration of how the seemingly ineffable act of writing is always grounded in particular instruments and media, from quills to keyboards. Along the way, we discover the candidates for the first novel written on a word processor, explore the surprisingly varied reasons why writers of both popular and serious literature adopted the technology, trace the spread of new metaphors and ideas from word processing in fiction and poetry, and consider the fate of literary scholarship and memory in an era when the final remnants of authorship may consist of folders on a hard drive or documents in the cloud.

A new "textual studies" and archival approach to the investigation of works of new media and electronic literature that applies techniques of computer forensics to conduct media-specific readings of William Gibson's electronic poem "Agrippa," Michael Joyce's Afternoon, and the interactive game Mystery House. In Mechanisms, Matthew Kirschenbaum examines new media and electronic writing against the textual and technological primitives that govern writing, inscription, and textual transmission in all media: erasure, variability, repeatability, and survivability. Mechanisms is the first book in its field to devote significant attention to storage-the hard drive in particular-arguing that understanding the affordances of storage devices is essential to understanding new media. Drawing a distinction between "forensic materiality" and "formal materiality," Kirschenbaum uses applied computer forensics techniques in his study of new media works. Just as the humanities discipline of textual studies examines books as physical objects and traces different variants of texts, computer forensics encourage us to perceive new media in terms of specific versions, platforms, systems, and devices. Kirschenbaum demonstrates these techniques in media-specific readings of three landmark works of new media and electronic literature, all from the formative era of personal computing: the interactive fiction game Mystery House, Michael Joyce's Afternoon: A Story, and William Gibson's electronic poem "Agrippa."
