Besides, Google has explained that there is a workaround: To search your library, just plug your parameters into this sample formula: <a href="http://books.google.com/books?hl=en&as_coll=0&start=0&num=10&uid=44483708056731249&q=mad">http://books.google.com/books?hl=en&as_coll=0&start=0&num=10&uid=44483708056731249&q=mad</a> * The as_coll=0 parameter defines which bookshelf you search within.
