  More than five years after their emergence, altmetrics are still seen as a
promise to complement traditional citation-based indicators. However, no study
has focused on their potential usefulness to capture the impact of scholarly
books. While recent literature shows that citation indicators cannot fully
capture the impact of books, other studies have suggested alternative
indicators such as usage, publishers' prestige or library holdings. In this
paper, we calculate 18 indicators which range from altmetrics to library
holdings, views, downloads or citations to the production of monographs of a
Spanish university using the bibliometric suite PlumX from EBSCO. The objective
of the study is to adopt a multidimensional perspective on the analysis of
books and understand the level of complementarity between these different
indicators. Also, we compare the overview offered by this range of indicators
when applied to monographs with the traditional bibliometric perspective
focused on journal articles and citation impact. We observe a low presence of
altmetric indicators for monographs, even lower than for journal articles and a
predominance of library holdings, confirming this indicator as the most
promising one towards the analysis of the impact of books.
