Google makes it even easier for readers to part with their hard-earned cash:
Today, we’re taking a big step towards bringing more books, across more sites, to more people online.
We’re launching a set of free tools that allow retailers, publishers, and anyone with a web site to embed books from the Google Book Search index. We are also providing new ways for these sites to display full-text search results from Book Search, and even integrate with social features such as ratings, reviews, and readers’ book collections. By providing tools that help sites connect readers with books in new and interesting ways, we hope publishers and authors will find even wider audiences for their works.
