After their manuscript has been accepted for publication, authors are required to pay a publishing fee of 470 euro, which covers the cost of the scientific publishing work flow, print and distribution of one print copy of the book for the corresponding author, server and repository costs as well as the book marketing. This fee is considerably lower than the ones charged by most open access publishers.
However, from the moment their work is published online, authors receive annual author royalties. Royalties are based on the number of downloads of a given publication, which can easily be tracked at sciyo.com. After the initial 100 downloads, 0.2 euro is accredited to the author for every 10 downloads.

The breakeven number of downloads is 23,500. It would take me all day to download that many, even if I could find enough unique computers on campus.
