But to come back to the point mentioned at the beginning cheap finasteride 5 mg otc, that publishers are an important supervisory factor for the quality of our texts order 1 mg finasteride fast delivery. In principle, supervisory bodies make sense, but are publishers the right ones for the job? Furthermore, which member of a medical publishing house should have been allowed to decide at the beginning of May 2003 – when even the specialists had only been aware of the extent of the SARS epidemic for six weeks – whether it was a sensible move to publish SARS Reference or not? Who has the right to decide whether something written by someone who has been practising his profession for 20 or 30 years should be published? The short-term image boost is stronger if your book is published by an established publishing house. The arguments that go against an author having a contract with a traditional publisher are: ƒ as a rule, you have to cede the rights to your own text; ƒ it is seldom possible today to persuade publishers to present a free parallel publication of the text on the internet; ƒ producing your own book can be considerably more lucrative. Thus, the following speak in favour of publishing your medical textbook by yourself: 1. The better establishment of your textbook in the long-term, since the parallel publication of a text both as a book and an internet version is still rare today. This gives you a selective advantage over authors who continue to publish their texts as books only. And of course, most important of all: you keep hold of the power. Just imagine if I had 18 What is financially feasible? NET, no Amedeo, no Flying Publisher – all because of one bad decision. We therefore advise all colleagues to produce and market their textbooks themselves. Print: the share that print costs have in the retail price depends on the size of circulation and the price. HIV Medicine 2005: 50 Euro for 800 pages), at a circulation of 500 copies, the printing costs amount to 14 Euro per copy, or 28% of the retail price, for 1000 copies 10 Euro, or 20%, and for 2000 copies 6. Distribution: the share of distribution costs amounts to approximately 45% of the retail price. This percentage is irrespective of the distribution channels (book wholesaler, sponsors). Profit: depending on circulation, profit is somewhere between 27 (100% - 45% - 28%) and more than 40% (100% - 45% - 13. The future reader (R) goes into a bookshop (B) and pays the retail price (yellow arrow). The bookseller or wholesaler pays the publishing house (X) after deducting a sales margin of 30 to 45%. The publisher has previously transferred payment for the printing costs to the print shop (P) and pays the authors off over several months or years. The thickness of the yellow arrows reflects the volume of money which flows. The publishers are out of the game and the authors market the books directly through the most important specialised medical bookshops. The future reader (R) goes into the bookstore (B), pays the retail price, and the bookseller remits 70% of this to the authors (A). The authors have previously transferred payment of the printing costs to the print shop (P). The thickness of the yellow arrows reflects the volume of money which flows. In this diagram, we have replaced the bookstore with a sponsor, such as a foundation (S). The sponsor pays the authors for the discounted books, and the authors in turn pay the printer (P). The reader (R) generally receives the books free of charge and is grateful (blue arrow). One or more sponsors have taken on a circulation of 1000 books and give the books away to doctors who are interested.
