Jerome Kassirer, the editor of NEJM in the 90s, has written a "blistering critique" of trends he saw in the management of the NEJM and its mismanagement by its owner, the Massachusetts Medical Socieity, which treated it as a "cash cow."
Kassirer's book is self published, and is available on Amazon as an ebook and in hard copy from Kassirer himself (here, here; "Unanticipated Outcomes: A medical memoir.") It's probably the first self-published book to get a featured review from LANCET (here).
