What is a bnc number?

A BNC number, or British National Corpus number, is a unique identifier assigned to each written text or spoken recording within the British National Corpus. The BNC is a large corpus of contemporary British English, encompassing a wide range of genres and registers. The BNC numbers facilitate the retrieval and analysis of specific texts within the corpus. These numbers are crucial for researchers studying language, linguistics, and related fields who need to reference or cite particular texts accurately. They are typically structured in a specific format that allows for easy identification and location within the corpus.
