Patterns and methods of scholarly communication have changed with the growth in information technology, particularly the Internet and the social web. 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 provided Altmetric scores – a measure of impact through social and mainstream media. The full list of PLAAS outputs showed a composition of 54% grey literature and 46% journal articles and monographs. Given that over half of PLAAS research outputs were in the form of grey literature, and therefore not indexed in traditional bibliometric databases, we suggest that alternative metrics be used in conjunction with bibliometrics, to measure the impact of a body of work on the scholarly domain. Although the bibliometrics in this study were a useful quantitative indicator of the impact of PLAAS research, this study was inconclusive with regard to determining the impact of the research output via altmetrics, partly because not any of the grey literature, nor any author from PLAAS, had a unique identifier, thus making it difficult to track and find quantitative indicators. Nonetheless, the potential benefit for PLAAS of using altmetrics was demonstrated in selected case studies of the output of three PLAAS researchers active on social media platforms.
