The idea of the Open Science Directory started with a request of IOC/IODE to create a database of all accessible journals in oceanography and marine science. The A-to-Z-list of EBSCO was the perfect tool to organize this collection. It was an easy step to extend this collection to a general directory of journals accessible in developing countries. With the help of EBSCO, it was possible to create the Open Science Directory, which started on February 14, 2008. Access to scientific literature is very important for the scientific work of every scientist but is often extremely difficult to obtain in developing countries. As a result of different projects a large collection of e-journals is now available for researchers in developing countries. The number of Open Access Journals is growing steadily as we can see in the Directory of Open Access Journals. Major UN organizations like WHO1, FAO2 and UNEP3 have their specific programs for the scientific institutions in low-income countries: HINARI4, AGORA5, OARE6. Finally a lot of universities, institutes and publishers have access to supporting programs. The most important are INASP-PERii7, eIFL8, Highwire9, JSTOR’s Developing Nations Access Initiative10 and eJDS11. ; Supported by IOC for IODE. ; Document available in English. ; Unpublished
