BioOne's goal is to enable specialized communities of researchers to interact meaningfully from all corners of the world. The project began as means for not-for-profit society journals to provide electronic subscriptions to their publications. One-third of BioOne's collection of 125 organismal biology journals is indexed as ecology, environment, or conservation science by ISI. The balance of the collection offers complementary primary resources as well as access to the critical “classics.” Access is free to the abstracts of all BioOne's 65,000 articles, and the collection is indexed by Google, Yahoo, and MSN Live Academic searches to ensure discoverability. To help those researchers who do not have subscriptions to BioOne, or who may be out of range from their institutional collections, over the past 6 years, we have added a growing body of Open Access articles, issues, and full volumes along with the ability to search just the OA content. In addition, partnerships with like-minded projects are enabling BioOne to build a diverse international research environment in which authors from 90% of the world's countries are now participating. These partnerships include such open access-friendly initiatives as Conservation International, Coalition on the Public Understanding of Science, Biodiversity Heritage Library Project, the National Science Digital Library, and OARE.
