“…Now more than ever, school libraries have “the capacity and the potential […] to collect, select, organize, and present in their area on the Internet resources of support for the development of reading and learning in the school” (Durban Roca, 2013), reaffirming their role as Resource Centres for Teaching and Learning (CREA) (Area Moreira and Marzal García-Quismondo, 2016; IFLA, 2015; Gobierno de España, Agencia Estatal, 2006, 2013). School libraries also represent a fundamental pillar for the achievement of information literacy (IL) (Blasco Olivares and Durban Roca, 2012; Campal García, 2006; Catalani, 2017; CILIP, 2014; Kim et al , 2014; Marzal et al , 2012; Pagán and Ortiz, 2016; Smith, 2016), of the key curricular competencies at all educational levels (Hanson-Baldauf and Hassell, 2009; Limberg et al , 2012; Martínez-Abad et al , 2017) and of the education of adolescents in such topics of major social relevance as immigration (Elizondo and Gorostiaga, 2016), bullying (Medina Santiago et al , 2017), equality (Muñoz Alvarado, 2013; Walker and Bates, 2016) and gender-based violence (Celis Ávila, 2004; Garro Fallas, 2014).…”
