Our vision is to crack this open by, first of all, encouraging academics to be aware of their rights, be aware of the lobbying that is going on, and also by enabling them to post their own publications over which they retain copyright, from their Mendeley profiles. A ton of papers have been made available by Mendeley in this way, by academics uploading their own papers. So, that’s our attempt at making content more accessible and science more open."
Quoted from the founder in an interview just a few months ago (17 September 2012). Speaks for itself really.
