“…In PlumX for example, the metrics available include usage (clicks, views, downloads, library holdings, video plays), captures (bookmarks, favourites, reference manager saves), mentions (blog posts, news mentions, comments, reviews, Wikipedia mentions), social media (tweets, +1s, likes, shares) and citations (citation indexes, patent citations, clinical citations, policy citations) [12]. Many studies have been done on the advantages and disadvantages of altmetrics and potential correlations to citation counts [13,14] and if researchers have an appetite and willingness to use more metrics such as usage data [15]. Whilst this paper does not go into the pros and cons of alternative metrics, we realise a growing willingness to use such metrics in the available "basket of metrics".…”
