“…The second stream of work examines whether existing metrics for evaluating journals accurately characterise OA journals with a twostage publication process (Bornmann et al, 2010). The third, and largest, stream of work examines the advantages of OA (Dong et al, 2006;Davis and Fromerth, 2007;Sotudeh and Horri, 2008;Sotudeh and Horri, 2009;Gentil-Beccot et al, 2010;Gaulé and Maystre, 2011;Koler-Povh et al, 2014;Wang et al, 2015) with the main focus on the scientific impacts of OA publishing. Papers deposited in open repositories receive higher numbers of citations (Davis and Fromerth, 2007;Gentil-Beccot et al, 2010;Koler-Povh et al, 2014), but there is no agreement on whether this effect is attributable to the open and early accessibility of deposited papers (Gentil-Beccot et al, 2010) or to their quality (Davis and Fromerth, 2007;Koler-Povh et al, 2014).…”
