• Written Corpora: The Brown Corpus is not only the first corpus, but it is at the same time the
first written corpus of English in modern times. The texts that make up the corpus data are
collected from written media, sampled from15 categories. A counterpart of the Brown Corpus,
the Lancaster-Oslo-Bergen Corpus of British English (LOB), is constructed following the same
principles of the Brown Corpus, and thus they have collectively come to represent varieties of
the same language, providing a reliable means of comparison between two varieties of English.
Later, in the early 1990s, the Freiburg-LOB Corpus of British English (FLOB) and the Freiburg-
Brown Corpus of American English (Frown) were developed to represent written American and
British varieties of English. Furthermore, comparisons of these two Freiburg corpora with
previous Brown/LOB corpora revealed data on language change in the time span between the
60s and the 90s.
