The document discusses the role of a compilation editor for radio news bulletins. A compilation editor reviews news items from various sources and organizes them into categories for bulletins. The editor further selects and trims news items for each bulletin, considering the bulletin's duration and audience. Headlines are chosen to highlight important stories. The editor also ensures news is written in a clear, concise style appropriate for audio broadcast in terms of sentence length, language complexity, tense, figures and undefined technical terms.
