Literature reviews are a genre that many graduate students do not fully understand and find difficult to write. While the genre, language and rhetorical moves of literature reviews are widely researched, less research focuses on citation use in literature reviews. Teaching students 'how-to' write the literature review through explicit genre awareness is not enough. What is needed, is a focus on the discursive nature of citations since citations are a core ingredient in literature reviews. The complexity of citing, referencing and using sources is difficult to teach in university classrooms, especially in courses that focus on content knowledge. When it is taught, it is often imparted to students as conventions with particular organisational features around citation styles. Or it is taught within the discourse of morality and academic dishonesty that surrounds plagiarism. What is lacking is a pedagogy that relates citing to the more complex discursive practices that are implicit and deeply embedded in particular time-bound contexts. The purpose of this research was to explore citation patterns in 23 draft and final masters' student literature review papers to better understand the ways in which students use sources in literature reviews with the aim of informing pedagogy. Findings indicate that the concept of intertextuality, specifically, transgressive intertextuality, intertextual engagement and discursive intertextuality can help with the teaching and learning of literature reviews and citation use.
