The purpose of this paper is to explore the discourse structures of translators' epilogues written by three business book translators. This study arrived at two findings based on the triangulation approach combining semi-structured one-on-one interviews and move analyses on 53 epilogues. First, this study found that publishers prefer source-oriented epilogues that they think could promote the commercial success of translated books. Second, this study found statistically significant differences between the three translators’ epilogues in terms of the proportion of TT-related moves. These two findings strongly support the notion that epilogues are shaped by complex and diverse interactions between the norm in the industry and translators with distinct career backgrounds and capabilities.
