microsoft live book search with fulltext download

I just have a chance of looking at Microsoft live book search demo , it's still a small collection, so search results can be confusing. However an entire book can be downloaded from archive.org as a PDF file, such as this one:

http://www.archive.org/download/writingsofcharle01dickuoft/writingsofcharle01dickuoft.pdf

I guess this is part of deal of Open Contents Alliance. Google Print doesn't really allow download of a full book.
