Nephrologia, or the ambiguities

"I was looking for open access articles in PubMed...and one article that came up was NEFRONA project: open-access database from the journal Nefrologia. There was no abstract in PubMed, so I followed the citation to the journal website from a link in PubMed....Yes, there was free full text on the web site, and I decided to check their publication guidelines in English in order to see how well they documented a green or gold open access policy....They seem to want the traditional publisher status of copyright holder, but they also give the articles away from their web site. I would like to suggest that they consider an additional clause granting the author the ability to store a green pre- and post-print pre-publication copy, perhaps as other journals do, with a link pointing to the final published copy...."
