“By “open access” to [peer-reviewed research literature], we mean its free availability 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.”

Researchers engage in discovery for the public good, yet because of cost barriers or use restrictions imposed by other publishers, research results are not available to the full community of potential users. It is our mission to support a greater global exchange of knowledge by making the research published in this journal open to the public and reusable under the terms of a Creative Commons BY-NC-SA license.

Furthermore, we encourage authors to post their pre-publication manuscript in institutional repositories or on their Web sites prior to and during the submission process, and to post the Publisher’s final formatted PDF version after publication. These practices benefit authors with productive exchanges as well as earlier and greater citation of published work.
