The changes have necessitated a broader definition of scholarly communication and the role of social media in the research process. We sought to record the body of work that the Institute for Poverty, Land and Agrarian Studies (PLAAS), a research institute at the University of the Western Cape, produced over a 20-year period (1995–2015) – the first two decades of its existence – and to measure its visibility and impact using bibliometrics and altmetrics. A survey was also carried out to investigate to what extent PLAAS researchers knew and used social media in their research practice. Scopus and Google Scholar were used as citation indices and Altmetric.com provided Altmetric scores – a measure of impact through social and mainstream media.enBibliometricsAltmetricsResearch outputsScholarly communicationGreyArticle
