“…Besides citation counts, a diverse range of indicators have been examined to assess the quality and impact of books. These include the number of libraries holding a book (Torres-Salinas and Moed, 2009;White et al, 2009), book reviews from scholars (Gorraiz et al, 2014;Sorli Rojo et al, 2011;Zuccala and van Leeuwen, 2011) and from readers that are not necessarily scholars (Kousha et al, 2017;Zuccala, Verleysen, Cornacchia and Engels), publisher prestige (Giménez-Toledo et al, 2013) and mentions from online course syllabi (Kousha and Thelwall, 2016;Mas-Bleda and Thelwall, 2018). A study of multiple indicators (Scopus citations, Mendeley captures, Goodreads captures, tweets, Wikipedia mentions, reviews in Goodreads and Amazon, EBSCO PDF views and saves and WorldCat library holdings) for a sample of 70,000 ebooks concluded that books should be evaluated using a range of indicators (Halevi et al, 2016).…”
