Why did so many early modern scientific authors dislike and distrust the printing press While there is no denying the importance of the printing press to the scientific and medical advances of the early modern era a closer look at authorial attitudes toward this technology refutes simplistic interpretations of how print was viewed at the time. Rather than embracing the press scientific authors often disliked and distrusted it. In many cases they sought to avoid putting their work into print altogether. In Loath to Print Nicole Howard takes a fresh look at early modern printing technology from the perspective of the natural philosophers and physicians who relied on it to share ideas. She offers a new perspective on scientific publishing in the early modern period one that turns the celebration of print on its head. Exploring both these scholars attitudes and their strategies for navigating the publishing world Howard argues that scientists had many concerns including the potential for errors to be introduced into their works by printers the prospect of having their work pirated and most worrisome the likelihood that their works would be misunderstood by an audience illprepared to negotiate the complexities of the ideas particularly those that were mathematical or philosophical. Revealing how these concerns led authors in the sciences to develop strategies for controlling circumventing or altogether avoiding the broad readership that print afforded Loath to Print explains how quickly a gap opened between those with scientific knowledge and a lay publicand how such a gap persists today. Scholars of the early modern period and the history of the book as well as those interested in communication and technology studies will find this an accessible and engaging look at the complexities of sharing scientific ideas in this rich period.
