Google Banned Books Viewer?

The news from GoogleBlog indicates that Google Book Search can now access some banned books, and it also provides a dedicated banned book index page. Here is an excerpt:

"Now Google has joined the party. At google.com/bannedbooks, you can use Google Book Search to explore some of the best novels of the 20th century which have been challenged or banned. And while libraries and bookstores around the country celebrate the 25th anniversary of Banned Books Week with special readings, displays, and more, you just might end up with a visit to your local library or bookstore and an old favorite or a new discovery."
