As the design director of MIT Press, Cooper promoted the Bauhaus-influenced, modernist look of a large quantity of publications, including 500 books. She designed the first edition of "Learning from Las Vegas" (1972), the ground-breaking manifesto of Post-Modernist design, using radical variations on the Bauhaus style to produce the publication. A third influential book design was a collection of essays by Herbert Muschamp, titled "File Under Architecture" (1974). This was one of the first books to be typeset directly on a computer by the book designer. At the time, the only typeface available was monospaced Courier, but she used the capabilities of computer typesetting to achieve a new level of control over the detailed layout of each page.
