Open Access

Open Access is a publishing model that provides immediate, worldwide, barrier-free access to the full text of research articles without requiring a subscription to the journal in which these articles are published. Accordingly, readers are allowed to copy, use, distribute, transmit and display the work publicly and to make and distribute derivative works, in any digital medium for any responsible purpose, subject to proper attribution of authorship.

In this model, the publication costs are usually covered by the author's institution or research funds. These Open Access charges replace subscription charges and allow the publishers to make the published material freely available to all interested online readers. At the same time, authors who publish in Open Access journals retain the copyright of their article.
