I once made a book for Tiger.  I imported "high quality" games, from various
places.  There were about 50,000 of them.

I knew there were bound to be bad lines, so I put the book on random, and let it
run on FICS for about a week straight.

In one of my first games, I was mated in 12 moves.  And in book.

Books, especially those with over 25,000 games, are almost impossible to weed
down.  I have been using the same book for over 2 years with Fritz, and am now
using it with Deep Fritz.  I still see myself come out of book down 1.00 or so,
when using the book unoptimized.  Not very much, but I do still see it.

And that book has 80,000+ games.  And probably 15,000 games of learning.
