Code-switching (CS) is prevalent in bilingual communication. With the bibliometric method CiteSpace, this paper gives an overview of the 1319 bibliometric records (1998–2018) on CS selected from the Web of Science. A co-occurring keyword network and a co-citation network of these publications were constructed. Analyses on the high-frequency keywords, document co-citation, co-cited reference clusters, publications with centrality betweenness and citation bursts have been conducted. The results indicate that the landscape of CS research has been expanded from the initial focus on the lexical/conceptual aspect to today's in-depth explorations on language contact, language control, systematic pedagogy, etc. Topics related to ‘multimodality’, ‘translanguaging’, ‘switch costs’ and ‘automatic speech recognition’ can represent the emerging trends of CS studies in various perspectives, such as linguistics, social science, cognitive science and computer science.
