A ghost is wandering around the web: it is called open access, a proposal to modify the circulation system of scientific information which has landed on the sacred soil of scientific literature. The circulation system of scientific magazines has recently started faltering, not because this instrument is no longer a guarantee of quality, but rather for economic reasons. In countries such as Great Britain, as shown in the following chart, the past twenty years have seen a dramatic increase in subscription fees, exceeding by far the prices of other publishing products and the average inflation rate. The same trend applies to the United States.

Scientific communication in court is particularly important for the understanding of the process of post-academic science communication. The purpose of this study, carried out through a qualitative approach, is: 1) verify whether and how the dynamics of an expert`s science communication in court can be traced back to the problem of public science communication. 2) underline specific characteristics of science communication in court. 3) propose a sample of a "general table on science communication", in order to be a ble to a nalyse every possible communication between the different parties of a legal proceeding.

In the midst of a debate on access to information, the World Health Organization and the FAO have decided to develop a strategy to guarantee the right of poor countries to have free access to scientific publications. This right is often denied, mainly because of high subscription costs. For this reason, universities and research centres in southern countries must forego buying magazines, which are a valuable instrument for updating, and exchanging information on research and scientific issues. This choice has been made in an historical period when the industrialized world is marked by a knowledge-based economy.

There are forces, factors, and influences other than pending classical peer review that assure the quality of scholarship before formal publication.

Peer review is the evaluation method that has characterized the scientific growth of the last four centuries, the first four of what is called modern science, indeed. It is matter of scientific communication inside scientific community, a subject too poorly studied in comparison with its critical importance for a scientific study of science (science of science). Peer review has been used for scientific paper evaluation before publication (editorial peer review) and for research proposal evaluation before financial support (grants peer review). Both cases present similar pros and cons, so I will treat them as a unique method for scientific evaluation. While the method remained pretty unchanged all along the period, apart from communication technology with peers, science has tremendously changed its organization and its relevance to society. So, peer review is antique and well rooted in practise, but its historical aim should now to be contrasted with the present situation of actual research, practises and social involvement of science.
