This journal provides immediate open access to its content, based on the principle that offering the public free access to research helps a greater global exchange of knowledge and thus meets the definition of Open Access of the Initiative of Budapest Open Access:

By "open access" to [peer-reviewed scientific literature], we mean their free availability on the public Internet, allowing any user to read, download, copy, distribute, print, search or use them for any lawful purpose, without any financial barrier, legal or technical, apart from those that are inseparable from those involved in accessing the Internet itself. The only limitation on reproduction and distribution, and the only role of copyright in this domain, should be to give authors control over the integrity of their works and the right to be properly credited and cited.

The journal does not impose article processing costs, shipping costs, or any other required charges on authors. Our mission is to support greater global knowledge sharing by making the research published in this journal open to the public and reusable under the terms of the Creative Commons Attribution-NonCommercial 4.0 Creative Commons License.

The journal's open access policy is registered with Sherpa/Romeo. Sherpa/Romeo is an online resource that aggregates and presents the open access policies of publishers and journals from around the world.
