Open Access Policy

The journal provides immediate open access to its content on the principle that making research freely available to the public supports greater global exchange of knowledge. By "open access" to this literature, we mean its free availability on the public internet, allowing any user to read, download, copy, distribute, print, search, or link to the full text of this article, crawl it for indexing, forward it as data to software, or use it for any other lawful purpose, without financial, legal or technical obstacles other than those inseparable from gaining access to the internet itself. The only restrictions on reproduction and distribution, and the only role of copyright in this domain, should be to give authors control over the integrity of their work and the right to be properly acknowledged and cited.
