Scientific Commons.org is a
search engine for scientific publications made available via open access repositories. These repositories include institutional repositories such as the California Digital Library’s e-Scholarship, as well as discipline-based repositories. The major aim of the
project is to develop the worlds largest communication medium for scientific
knowledge products which is freely accessible to the public. A key challenge of the project is to support the rapidly growing number of movements and archives who admit the free distribution and access to scientific knowledge. These are the valuable sources for the
ScientificCommons.org project. The ScientificCommons.org project makes it possible to access the largely distributed sources with their vast amount of scientific publications via just one common interface. ScientificCommons.org identifies authors from all archives and makes their social and professional relationships transparent and visible to anyone across disciplinary, institutional and technological boundaries. At the time of this posting, ScientificCommons.org included nearly 25 million documents from around 100 different repositories around the world.
