The scholarly communication system is in a critical stage, due to a number of factors. The Open Access movement is perhaps the most interesting response that the scientific community has tried to give to this problem. The paper examines strengths and weaknesses of the Open Access strategy in general and, more specifically, of the Open Archives Initiative (OAI), discussing experiences, criticisms and barriers. All authors that have faced the problems of implementing an OAI compliant e-print server agree that technical and practical problems are not the most difficult to overcome and that the real problem is the change in cultural attitude required. In this scenario, the university library is possibly the standard bearer for the advent and implementation of e-prints archives and Open Archives services. To ensure the successful implementation of this service the Library has a number of distinct roles to play.
