Non-fictionWhen an editor works on a book, they balance reader expectations with what they interpret the author’s intentions to be and use their experience to make suggestions. This might mean changing some of the language to ensure the work is comprehensible for general readers, or asking for more detail where a setting has been hastily described. An editor will always be anticipating the market, and their extensive reading of contemporary works makes them well-placed not only to understand the social and political conditions of the day but also trends in publishing and marketing.
