What is a Manifold project?

A Manifold project is iterative and expansive. A Manifold project begins with the author and their willingness to think beyond the normal confines of the traditional print strictures. Allowing for a much more expansive archive of primary sources, such as field notes, moving images, audio, interactive data and maps, photographs, interviews, and archival material, a Manifold project asks that an author think creatively about the broad set of materials that are collected in the process of researching and writing a book. A Manifold project can be iterative, showing how a book evolves in real time, drawing on the collective expertise of early readers to crystallize its core arguments. Early drafts of chapters, journal articles, and field notes can show, long before the finished book is published, the author's arguments evolving and resonating with a community of readers.

Where does Manifold come from?
The seeds for Manifold Scholarship were planted during the collaboration between the University of Minnesota Press, the Graduate Center at the City University of New York, and Cast Iron Coding to create a web edition of Debates in the Digital Humanities, edited by Matthew K. Gold. In 2015, with funding from the Andrew W. Mellon Foundation, development began on Manifold, adapting what we learned from building the Debates prototype website into a platform that would scale for the publication of many books, and could be used by many different publishers. Recognizing that books are projects that begin long before a final manuscript is submitted to a publisher, Manifold enables authors to work with their publisher to post texts, research materials, and media from their research and writing in progress and to receive community feedback.
