 For example, a wide variety of imaginative texts (novels, short stories, poems, and drama scripts) were included in the BNC, but such inclusions were deemed useless as researchers were unable to easily retrieve the subgenres on which they wanted to work (e.g., poetry).Because this metadata was omitted in the file headers and in all BNC documentation, there was no way to know whether an "imaginative" text actually came from a novel, a short story, a drama script or a collection of poems unless the title actually included words such as "novel" or "poem").With the 2002 introduction of a new version, the BNC World Edition, BNC attempted to deal with this problem.
