The British mass-market publisher Penguin produced a number of texts on psychiatric topics in the period c.1950– c.1980. Investigation of editorial files relating to a sample of these volumes reveals that they were shaped as much by the commercial imperatives and changing aspirations of the publisher as by developments and debates in psychiatry itself. A number of economic imperatives influenced the publishing process, including the perennial difficulty in finding psychiatrists willing and able to enter the popular book market; the economic (...) pressures exerted on peer-review protocols; and the identification of a niche market in popular psychiatry, latterly of a politically radical flavour. As well as offering a materialist standpoint for the study of popular psychiatric texts, this investigation allows an opportunity to adapt, apply and assess theoretical approaches to mass-market publishing by psychiatrists.
