In recent years, the growth of Open Access journals reflects the increasing interest of publishers and researchers in Open Access publications. According to the Scopus data, there has been a growing trend in the ratio of Open Access journals to all journals. Research has shown that articles published in Open Access journals tend to be viewed and cited more in comparison with articles published in subscription-based journals. Publishing articles in Open Access journals may boost the number of received citations by up to 10% . It is clear that an article published in an Open Access journal that is available on the web may be read and indexed by web-based search engines, so it will potentially receive more citations.
