In academia we constantly need to write project proposals and apply for funding. Sometimes it helps to read what others have already tried or written in order to learn from them.
I wonder whether there is somewhere a repository or database of freely available project proposals that research groups or companies have written when they have applied for funding to some funding agency (seventh european framework in Europe, National Science Foundation in USA, in industry I do not know, etc), and of course, that have been successful. Also would be great to access to unsuccessful proposals and to understand why the failed in the call.
