During the eighteenth century, the Edinburgh Medical School made Edinburgh an internationally renowned medical centre. An entrepreneurial network of Scottish publishers founded journals and periodicals to publish the research of the city's medical men. A quarter of John Murray's imprints were medical books and he published the first commercial medical journal. In this innovative interdisciplinary study, Macdonald examines the development of medical periodical publishing in Scotland from 1733 to 1832, using evidence from the medical press itself as well as records of booksellers and publishers. She shows how medical and scientific societies, medical practitioners, editors and booksellers all had a hand in creating, shaping, sustaining and producing authorized medical knowledge.
