Why is free dissemination of scientific results so important? For several reasons. One. It is a moral obligation to grant members of the public free access to scientific results that were obtained through public funding, through taxpayers’ money. I get particularly irritated when I read in my newspaper that new scientific results have been published on, say, sea level rise, to find out that I have to buy the latest issue of Nature Magazine to be properly informed. Two. Scientific knowledge provides a competitive edge to modern ‘knowledge based’ societies and economies. Educational research, research on public health, on informatics, genetics, energy, on anything: results should flow freely into society and into the private sector to find their way into our daily life and into economic growth. Three. Science itself will benefit from a borderless information flow between scientific fields. In order to face the ‘grand challenges’ of today scientific disciplines have to cooperate and new disciplines will emerge. In the next decades the world population will grow to 9 billion. Energy, food, ageing – three issues that are an enormous challenge. Urbanization, logistics are two additional ones. Addressing them requires effective collaboration of researchers in all fields: social sciences, humanities, life sciences, natural sciences. An optimal communication between these researchers, through Open Access publishing, is essential for this effective collaboration to happen. Moreover, the availability of a comprehensive body of quality controlled (peer reviewed!) publications in big ‘findable and searchable’ databases will allow scientists, helped by intelligent, new ‘search engines’ to make new and unexpected interdisciplinary discoveries.” [to be continued...]
