This chapter explores the process involved in selecting a topic that can attract a broader readership. As outlined in the chapter, writers should keep their eyes and ears open to observe events in both their immediate and distant surroundings.

The writer’s interest, knowledge and expertise in a specific field are equally crucial factors. These elements, when combined with market potential and the opportunity for a wider readership, contribute to the creation of engaging nonfiction. The chapter offers guidance on pinpointing subjects that can be developed into comprehensive nonfiction works.
