ScientificCommons

ScientificCommons aims to provide the most comprehensive and freely available access to scientific knowledge on the internet.

The major aim of the project is to develop the world's 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. Currently ScientificCommons.org has indexed over 23 million scientific publications and successfully extracted over 6 million authors' names out of this data.
