Authentic Russian Material

[Loren Allen Billings]

Perhaps the best collection of authentic material is the Uppsala Russian
Corpus, put out by Uppsala Univ. in Sweden, and--last I heard--costs
the equivalent of about USD 600, so it aint cheap.  One person who helped
in its compilation is Prof. George Fowler (gfowler at indiana.edu), I suppose
he could advise you on whether it is what you're after.  He also has a
number of texts of his own which he distributes upon request.  Hope this
helps.  --Loren Billings (billings at princeton.edu)
