Multinational publishers are also big businesses with increasing pressures on sales, costs and profits. Books come and go more quickly, have reducing production standards, and are produced by overworked staff. Big publishers make more money . Fewer rights, lower royalties, less marketing, less international exposure, longer schedules, less flexibility, less attention from staff and no better books. But they do often pay as high or higher royalties and sell just as many or more books.
Books endure with big established publishers.
Profit pressures lead to ruthless 'pruning out' of 'non-performing' titles. Smaller publishers need you more. Furthermore a digital publisher can easily update your work. Not everything is at it seems, and not all promises from multinational publishers should be accepted without a large dose of sceptical salt. It is not intended to give offence, and should not be relied upon by any person without first seeking further information from a professional source.
