The 1930s BROWN Corpus (B-Brown)

Like BLOB-1931, this corpus belongs to the same family of corpora as Brown, LOB, and FLOB. B-Brown extends the chronological span of the Brown corpora, providing an empirical basis for the study of written American English in the first half of the twentieth century. It follows the same sampling criteria originally designed for the Brown corpus of written American English but samples texts from the period 1928-1934.

Currently available for on-site access at Zürich University only. We hope to make it available on-line with limited access (context) in the near future.


Stefanie Dose, Nina Lötsch, Melanie Röthlisberger and Kerry O’Reilly were involved in text acquisition and digitization of the corpus at various stages, Gerold Schneider added syntactic annotation (PoS-tagging and parsing).


B-Brown exists in two formats:

  • untagged plain text
  • non-PoS-tagged XML version

A PoS-tagged and parsed version of the corpus is searchable locally at Zürich University.
