Open access implies the free availability of scientific and academic content on the Internet. Users can not only consult them for free but also can download, copy, print, distribute or cite them. Open access provides greater accessibility to documents and greater visibility for authors.
Open Access Policies range from broad support and promotion statements - international declarations - to more mandatory mandates from agencies that finance research, even in the form of laws, as well as institutional policies that declare their support for open access as a principle and encourage the scholars to publish this way.

DULCINEA: copyright rights and auto-archive conditions of Spanish scientific journals
In the open access the author maintains his rights and the dissemination is not exclusive. The work is protected by copyright law and Creative Commons licenses collect the uses that the author allows on their work to other users.
