“…The impact of scholarly publications has been traditionally assessed using the two most widely used citation-based databases, the Web of Science (WoS) and Scopus, which cover mainly mainstream English-language journals (Archambault et al, 2006). This coverage bias marginalises social sciences and humanities research (Caerols Mateo et al, 2017), which usually has a stronger national and regional interest (Hicks, 1999), tends to be published in the language of the nation or culture that is studied rather than in English (Engels et al, 2012;López-Navarro et al, 2015;Moed et al, 2002), and in national journals rather than in international journals (Larivière and Macaluso, 2011). For some social scientists, and many humanities scholars, monographs and book chapters play an important role in scholarly communication (Huang and Chang, 2008;Leydesdorff and Felt, 2012;Nederhof, 2006;Romanos de Tiratel, 2000;Sivertsen, 2016;Sivertsen and Larsen, 2012;Thompson, 2002).…”
