Comparison of subscription access and open access obstetrics and gynecology journals in the SCImago database

Objectives: The aim of this study is to compare the annual SJR and to evaluate the other parameters that show the scientific effect of journals in terms of open access (OA) or subscription access (SA) in the field of obstetrics and gynecology according to the SCImago database.Material and methods: This study was conducted between September-December 2019 at Near East University. The SCImago Journal & Country Rank database was used to collect information about the journals. We evaluated and compared the changes in the one-year SJR (SCImago Journal Rank) and journal impact factor (JIF) of OA and SA journals.Results: Data from 183 scientific journals in the field of obstetrics and gynecology from the period between 1999 and 2018 were evaluated, where 140 of these journals were SA and 43 were OA. The average SJR of OA journals in 1999 was 0.17, while it was 0.38 for SA journals. In 2018, these values were 0.31 and 0.78 for OA and SA journals, respectively. In the comparison of JIF, the average of the OA journals in 1999 was 0.09, while it was 0.66 for SA journals. In 2018, these values were 0.80 and 1.93 for OA and SA journals, respectively.Conclusions: Access to information has become easier due to technological developments and this will continue to affect the access policies of journals. Despite the disadvantages of predator journals, the rise of OA journals in terms of number and quality is likely to continue.
