One of the important indicators of the level of scientific and technological development of a country is the number and quality of publications produced therein. Such publications listed in international citation indexes tend to function as a leverage to streamline the scientific, human and economic development. Citations to these publications show the contribution of that country to the science in general, too. This paper investigates some of the bibliometric characteristics (impact factors, article influence scores, quartile and percentile values, and h indices) of journals that are published in Turkey and indexed in the Web of Science citation databases. Based on journal impact factors (and the other measures based thereon), a comparative review of the progress between 2006 and 2015 and the impact of Thomson Reuters' regional expansion policy on journals has been carried out. Findings show that the impact factors of journals, although relatively improved, have not increased as much as is desired during this period. The impact of papers published in these journals is well below that of the world average of all journals in their respective subjects. Findings are discussed in relation to Thomson Reuters' regional expansion policy and their implications are interpreted in the context of academic promotion and research assessment policies currently in effect in Turkey.
