The importance and focus of the interview in the work of the print and broadcast journalist is reflected in several books that have been written on the topic. Most of these books as well as several chapters, mainly in, but not limited to, journalism and broadcasting handbooks and reporting texts, stress the 'how to' aspects of journalistic interviewing rather than the conceptual aspects of the interview, its context, and implications.
