Open access to the literature allows scientists in the developing world to read original research papers for free, which contributes to scientific advancement. Nonetheless, in these same countries, funds are not sufficient to pay the publishing charges made by some publications, including 'open access' journals. For this reason, many journals waive fees for scientists from developing countries who submit to them.

Although these waivers benefit the scientists who submit, part of the solution should also come from developing countries themselves. The support from funders must include provision for submission fees, so that government agencies that support research projects take responsibility for their investment. I echo the Salvador Declaration on Open Access for Developing Countries (www.icml9.org/meetings/openaccess/public/documents/declaration.htm) and I urge governments of these countries to consider the cost of publication as part of the cost of the research.
