Paradoxes of Open Access

Aim of my talk is to provide first of all a brief overview on the main problems related to OA in its currently different forms, in order to discuss more in detail some possible (partial) solutions, taking two fundamental questions in account: 1) which OA form should be preferred at the moment by young researchers, even considering the criteria underlying the evaluation (not only in Italy) of the quality of their scientific production, therefore of their career opportunities? 2) how should we evaluate the proposal of separating the editorial work of academic journals from the evaluation of the scientific quality of their papers, which should pertain to a public and independent authority?
