This dataset contains the researcher's annotation of thirty pieces of literary review writing assignments collected from six Chinese English-major undergraduates in a flagship Chinese university. The raw literary reviews are parts of the six students' coursework for their literary courses during their undergraduate period. The current study is concerned with the incorporation of multi-faceted external voices in Chinese English-major undergraduates’ literary review writing and writer stance from an engagement perspective. Potential longitudinal changes of their citation competence reflected in their writing samples were also detected. The data shows the student writers' use of three citation-related engagement sub-categories, namely acknowledge, endorse, and distance resources in their literary review assignments, as a reflection of their citation competence and authorial voice.
