This paper reports on a study of social media events relating to 28 Open Access (OA) monographs,published between 2014 and 2015. As with citations (Cronin 1981) social media events representthe frozen footprints of the journey that monographs take as they move through digitallandscapes. The study captured mentions of the study-set of monographs via Twitter, Facebook,Wikipedia and online blogs; as well as user ratings on Google Books, Amazon and Goodreads.Information relating to the ways in which the books were bookmarked and cited was capturedvia the online reference managing platform Mendeley. The benefits and limitations of differentaltmetrics approaches to capturing and analyzing this data are discussed. Practical suggestionsfor researchers interested in the application of Altmetrics approaches to studies of monographsare also provided.
