The article deals with the problem of the use of electronic open journal systems in scientific and pedagogical research as well as the formation of ICT competence of researchers on the use of such systems. The concepts of electronic journal system (EJS) are considered. The most common kinds of electronic journal systems are considered (proprietary, local (in-house), open and cloud journal systems). The criteria for accessing the effectiveness of the electronic open journal systems (EOJS) use in scientific and pedagogical research are distinguished (normative, organizational and communication, effective), as well as their indicators. The organizational and pedagogical model of EOJS use in scientific and pedagogical researches is developed. The definition of "ICT competence of researchers on the use of EOJS in scientific and pedagogical research" is provided; its components are distinguished; criteria (axiological, cognitive, praxeological, adaptive) and indicators of its formation are defined. The model of formation of this competence is provided. The main stages of the experimental process (2010–2018) are described. The results of the formation of ICT-competence of researchers and information-analytical monitoring of the scientific journals of the National Academy of Educational Sciences of Ukraine are presented.
