Docear

Docear is what we call an "academic literature suite". It integrates everything you need to search, organize and create academic literature in a single application: a digital library, reference manager, PDF and file manager, note taking and mind mapping. And the best: Docear works seemlessly with many existing tools like Mendeley, Microsoft Word, and Foxit Reader. Docear is free and open source, funded by the German Federal Ministry of Technology and developed by scientists from around the world, among others from OvGU, and the University of California, Berkeley.
