In the publishing industry it is customary for the publishing house to determine the price of the book. Of course, all the customers expect a lower price for their books. But please bear in mind that, when it comes to pricing, we can rely on years of experience in the publishing business. As we are financed exclusively through the selling of our books, we attach great importance to an optimal balance between profitability and marketability in fixing our prices. Academic reference books in principle have a higher price level than novels. You may also compare our prices to those of other scientific publishing houses. Besides, we offer our authors the unique opportunity to influence the market book price by acquiring a certain number of printed copies. We can offer to sell the book at a lower price if we can restore at least part of the production costs that we paid in advance as part of the publishing process, which is free of charge. Purchase however is not obligatory.
