What up with Google Books SERPS?

[bloard]

In one of my niches, the end of the results are full of listings for books.google.com. I am aware of the 950 penalty and assume these listings are there for that reason. However there are like 10-20 different listings for various books.google.com pages and they aren't indented. Just separate listings. I thought each subdomain/domain could only have 2 listings in each set of results?

What keywords yield these results?

Yeah a lot of Google books is showing in the results for some keywords i have seen some in the results but it's their own products and they are promoting in the regular way for sure they have a lot of backlinks from Google inner pages with high pagerank, i think it's the reason of ranking those books pages.
