In order for REAKTOR to publish and disseminate research articles, we need non-exclusive publishing rights (transferred from the author(s) to the publisher). This is determined by a publishing agreement between the Author(s) and REAKTOR. This agreement deals with transferring or licensing the publishing copyright to REAKTOR while Authors still retain significant rights to use and share their published articles. REAKTOR supports the need for authors to share, disseminate, and maximize the impact of their research and these rights in any databases.
As a journal author, you have the right to use your article for many purposes, including by your employing institute or company. These Author rights can be exercised without the need to obtain specific permission. Authors publishing in BCREC journals have wide rights to use their works for teaching and scholarly purposes without needing to seek permission, including, but not limited to:
