Translation in Systems, by Theo Hermans, the seventh book in the series Translation Theories Explained, edited by Anthony Pym, tackles the task of explaining the different translation theories by looking at both the descriptive and systematic approach to translating. Hermans explains that the purpose of his book is three fold: “to explain the descriptive and systematic approach to the study of translation; to engage critically with some of the key ideas; and to suggest possible directions for further theoretical and methodological reflection.” Hermans’ research for this book was conducted during a sabbatical term with support from the Humanities Research Board of the British Academy.
