To find out which journals and publishers grant advanced permission for 'green', i.e. gratis, open access, see the SHERPA RoMEO database and its statistics page.

UK universities and other research institutions have posted a lot of academic, educational and research information in a range of systems similar to our own UQ eSpace repository. A search tool has now been developed to make this material more accessible. The tool runs a federated search across the more than 130 repositories included.

PLoS One, published by the Public Library of Science, was launched in 2006. Last year, it became the largest scientific journal in the world, publishing nearly 7,000 articles. Foir impact, it is now ranked 12th in biology journals, not bad going for a journal less than 5 years old. PLoS One's success has led other players in the field think about launching open access journals.
