From the Bulletin of the World Health Organization (BLT), The impact of open access upon public health:
"Arthur Amman, President of Global Strategies for HIV Prevention (www.globalstrategies.org), tells the following story:
“I recently met a physician from southern Africa, engaged in perinatal HIV prevention, whose primary access to information was abstracts posted on the Internet. Based on a single abstract, they had altered their perinatal HIV prevention program from an effective therapy to one with lesser efficacy. Had they read the full text article they would have undoubtedly realized that the study results were based on short-term follow-up, a small pivotal group, incomplete data, and were unlikely to be applicable to their country situation. Their decision to alter treatment based solely on the abstract’s conclusions may have resulted in increased perinatal HIV transmission.”
Amman’s story shows the potentially deadly gap between the information-rich and the information-poor. This gap is not the result of lack of technology or of money, but of a failure of imagination. We live in the most information-rich era of history, when the Internet allows immediate global dissemination of crucial health information, and the inter-linking of online information creates an integrated, living body of information — the ultimate vision of which is the semantic web.(1)
What is preventing such a living web? For scientific and medical information, two obstacles are vested interests and traditions. Central to these traditions is the role of copyright, which was developed when the dissemination of work was on paper. Initially, applying copyright to medical articles protected both the intellectual investment of authors and the commercial investment of publishers...
Print is no longer the most efficient way to disseminate information. The Internet provides the means to revolutionize publishing in two crucial ways. First, it makes it possible to disseminate health information at no charge to anyone in the world with online access. Although it costs money to peer review, edit, produce, and host an online article, this is a one-time, fixed cost. If research funders are willing to pay this cost, then the published work can be made freely available to all readers worldwide, and there would be no need for journal subscriptions. This is one way of financing an open-access model of publishing. (2)
Second, because the Internet allows not just ease of access but ease of reuse, an article’s usefulness is limited only by a user’s imagination."
