Open Access Statement
We publish articles in all of our journals under a Creative Commons Attribution (CC-BY) license. This license permits the reuse for commercial purposes, but still requires that the article is fully attributed.
We also support Budapest Open Access Initative (BOAI), which means free availability of our content on the public internet, permitting any users to read, download, copy, distribute, print, search, or link to the full texts of these articles, crawl them for indexing, pass them as data to software, or use them for any other lawful purpose, without financial, legal, or technical barriers other than those inseparable from gaining access to the internet itself. The only constraint on reproduction and distribution, and the only role for 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.
